Dirty Denver

Windstorm

Windstorm

The wind blows here in Denver, and it is not all air.  Those mountains just west of us are wearing down.  Most of the sand and dirt ends up in the rivers, put the wind blows some of the mountains away.  If you park your car outside, you already know this.  The dust covers everything on the car, and you have to wash the damn thing.  Mostly the dust is that tan/brown dirt color, but sometimes it is red when parts of Utah decide to take a visit.

The constant deposition of wind-blown dirt is why ancient cities get buried.  The process is slow, but relentless.  Denver is being buried, but we haul a lot of it away.  Our older house has what seems to be sunken sidewalks.  It is the wind- blown dust combined with organic matter (grass clippings) to form topsoil.

Carol likes to say that a lot of the stuff that accumulates is spider legs.  True, along with the exoskeletons of millions of insects.  In geologic terms the rate of deposition of all that stuff is fairly rapid.

Here on Colorado’s Front Range we get wind, but nothing like the mountain winds, unless you live in Boulder or other places at the foot of the mountains.  The mountains are high enough to get some of the higher altitude winds that the flatlands don’t get much of.  Also, when a weather system blows in, the mountains act as a barrier, forcing all that moving air up.  As it rises, it cools, gets more dense, and descends on the lee side of the mountains. As it falls, it gains velocity and tends to warm up, creating our famous chinook winds.

Loess Soil Windblown Dirt

Windblown Dirt

As the wind moves on the plains, it’s velocity decreases and some of the dirt it carries falls out.  Close to the mountains, a lot of it is sand.  That explains the sand hills we have close to the mountains.  You can identify the sand because it does not support plant growth as well as soil.  Sandy areas are cow country, no farming.  A little farther east, the dirt falls down.  A lot of dirt falls down, forming loess, a German term for wind-blown dirt deposits.  Eastern Colorado has thousands of square miles of loess.  Without irrigation, it is usually planted in wheat.

Of course, all the water or wind-borne sediment is headed for Mississippi, Lousiana, or the gulf.  Most of that Mississippi mud will end up as shale.  At some point plate tectonics will shove it up as dry land and the cycle starts over.  Most of the sand will eventually end up in the streams, get buried, and form sandstone like the Dakota sandstone dinosaur fossils are found in.  In other places, tremendous deposits of wind blown sand accumulate, eventually forming the sandstone that blankets the Colorado Plateau.

That dirt accumulating in your lawn and garden is part of a recycling process going on all over our planet for millions of years.  The process will continue long after we are all gone, as long as there is air and water on the planet.  To me, the whole thing is a miracle, all these geologic processes creating conditions existing long enough for the evolutionary mistake known as humanity to develop.

Shaking and Baking

As you are aware if you are a regular reader of my ravings, I am a geology buff.  I like the Big Picture, mid-ocean rifts and rises, tectonic plates shoving one another around, places where the hot insides spout out of the ground, mountains rising and being worn away, and the oceans becoming ever more salty.  Most of the time, all this is a slow process, but sometimes all hell breaks loose.   

San Andreas Fault

San Andreas Fault

Just look at that photo of the San Andreas Fault.  Things are clearly on the move and the land is being torn apart.  The Pacific Plate is sliding northward along the North American Plate.  Pasadena will one day be next to Anchorage.  Don’t wait up for it, though.  The Pacific coast of North America is one of the most seismically active regions on the Ring of Fire surrounding the Pacific Ocean.  It shakes, it blows, it smokes, it flows.   

Places like that make nice places to live.  Most of the time.  There is the ocean, lots of pretty landscapes with beautiful mountains nearby,  and places to grow things.  Just look at the Seattle-Tacoma area.  Bays, inlets, rivers, islands, and a big old mountain to look at.  It is easy to forget that mountain is a large volcano just biding it’s time until it lets loose again.  

Mount Rainier. Close to Town

Mount Rainier. Close to Town

If Rainier resembles Mt. St. Helens in the way it erupts, there might be some warning.  What we won’t know is how big, exactly when, and for how long.  There is a lot going on in that area.  Boeing, Microsoft, REI, millions of people, and Starbucks are a few examples.  If a swarm of magnitude four earthquakes begin, what to do?  Shut everything down and evacuate?  Where will everyone go?  What about looting and plundering?  What if it doesn’t erupt for months, if ever?   

Pyroclastic flows of very hot, wet, chunky stuff have flowed off that mountain all the way to the ocean.  The old cliche says “It is not if, but when.”  We just do not know when.  So, life along the Pacific Rim is always something of a gamble.  I have felt small earthquakes and looked into the crater of a Volcano in Costa Rica, a lovely, green, paradise.  Earthquakes destroy roads and railroads, volcanos bury villages, and life goes on.   

Irazu, Costa Rica

Irazu, Costa Rica

Small, poor Costa Rica is one thing, the Seattle-Tacoma area, or Los Angeles, or Portland, or Eugene, or San Francisco are entirely different matters.  No amount of preparation can take into account all the things which might happen.  Prediction is in its infancy.  Mt. St. Helens in hindsight gave lots of warning, but the disaster was huge in a relatively isolated area.  When Rainier or Mt. Hood let go the disaster will be in a heavily populated area with just a few ways out. 

Currently there are lots of earthquakes in the oil field regions of Texas, Oklahoma, and surrounding areas.  I wouldn’t worry too much if I lived there, the odds of a Big One are fairly small.  St. Louis and Salt Lake are at more risk.  The West Coast is the big danger zone.  The earth will keep moving, the plates will continue to slide.  Eruptions and quakes will continue to happen.  My solution?  Don’t live there.  What is your plan?

More on Discontent

The Age of Steam

The Age of Steam

Our economy has been one of change since the beginning.  When the railroads came to Colorado in 1870, a lot of teamster jobs hauling freight from Omaha and Kansas City went away.  The automobile would not have happened without the new petroleum industry.  Coal retained its strength from powering locomotives, heating homes, and fueling industry.  Industry and manufacturing grew, making the American economy one of the largest in the world.

What a combination, land, natural resources, transportation, a growing population of people with ambition, mobility, and a willingness to try something new.  Some were left behind.  Native Americans, African Americans, and those new citizens in the Southwest who were once part of Mexico with its traditional ways.  As always, immigrants ended up at the bottom because of language and discrimination.

There were troubles.  Low wages, a turbulent labor history, drought, an unstable business cycle creating panics individuals were helpless to influence.  There were some adventures the government engaged in, such as Cuba, the Philippines China, Japan, all the trappings of empire.  In many ways the American West was an empire, won at the expense of those who were living there.

Agriculture was becoming more mechanized, displacing people who moved to the cities to work in industry.  All the change continues.  There is a tremendous amount of wealth in Silicon Valley, not so much in Michigan.

The West has been boom-bust from the start.  The fur trade collapsed, but the gold rushes started.  The government started giving land to the railroads and individuals.  The short grass prairie boomed with hopeful wheat growers, then the droughts came.  Oil and gas grew and grew, and grew.  As old fields played out, new oil fields were discovered.  A couple of big wars really heated things up.

It all looked great.  Yes, lots of change, but people could find good jobs and things steamed along.  The real upheavals were when the business cycle threw millions out of work.  The 1930’s were a terrible time, but a war healed all that.

The West That Never Existed

The West That Never Existed

The 1950’s seemed like a golden age.  Lots of jobs, the U.S. Ruled much of the world, and television built a myth of stability, prosperity, and a bright future for everyone.  the myth came from relative prosperity and the ubitiquous westerns on television promoting a life that never existed.

The 1960’s brought social upheaval accompanied by a growing shift in how people made their living.  Steel mills closed, imported cars were on the roads, and computer-driven automation started taking industrial jobs.  The word Yuppie became a term of derision, but the Yuppies were the wave of the future.  They possessed education and a skill set many people could or would not obtain.

The skilled trades fell out of favor. It is college or else.  The trade jobs are filled the way they have always been filled, by immigrants.  This time however, the immigrants are not easily assimilated Europeans.  They are Latin, and and bring their culture with them.  Many are just not as interested in assimilating, and many are undocumented.

All this change leaves a huge segment of our society out of the good life.  Many are rural, where big mechanized farms haven taken jobs.  Many just do not have social and intellectual requirements to move into the new economy.  What’s left?  Low-paying service economy jobs, often for an out of date minimum wage inadequate for one person, let alone a family.  It is hard to build a life mowing lawns and doing kitchen work.  Much of the time jobs that used to be stepping stones have turned into dead ends.

The trouble is just beginning.  Those people marginalized by an economy where they don’t fit can be radicalized and turn to violence and terror or Donald Trump, which may be same thing.  The discontent is just not with the marginalized working class.  There are lots of well-educated people from middle class families making pizzas and living in their parents’ basement.  They thought they were doing the right thing going into debt to get an education and found nobody wants them.

This is still a rich country.  There is a huge imbalance in the distribution of wealth which has to change.  The change agent must be government.  A true progressive tax structure and an end to the massive influence of special interests in government are desperately needed.  The nation has the resources to provide everyone with an income providing them some dignity and the flexibility to enhance their station in life.  Given a decent income, most will seek ways to do even better.

We will always have the wealthy and the poor.  Now, there is too much concentrated wealth for a few and too many poor.  Trying to revert to an American utopia which never existed will only add to social instability.

Happy Days Are Here Again

Happy Days Are Here Again

There should be no food banks or coat drives.  There should be no one sleeping on the streets.  People with mental health problems should not be cast out.  Everyone should have the time and resources available to build better lives for themselves rather than being trapped in poverty.

In other words, we need a new time of progressive change, not an attempt to return to a myth.  How to pay for it all?  A realistic progressive tax system to redistribute income.

The Summer Of Our Discontent

What a time!  It’s hot about two weeks early for this area.  I got a replacement toolbox for my Toyota Tacoma’s toolbox.  The old one failed because I haul so much stuff around.  Fortunately it had a lifetime guarantee.  We seem to be spending entirely too much time in doctor’s offices; me getting pre-cancerous patches frozen on my head, Carol with eye trouble, and her son with a broken wrist and atrial fibrillation.

On the positive side, our garden is looking great, no hail this year so far.   We are going to have a big raspberry crop, the flowers are beautiful, and all the veggies are growing away.  Things seem to be going fairly well for an old couple.

There is tragedy in the land.  Murdering large groups of innocent people just trying to have a good time is terrible.  There has to be some means in place to restrict weapons solely designed for killing large numbers of people.

Donald Trump Addresses GOP Lincoln Day Event In MichiganThe reason I am writing this, however, is about the current political situation.  The U.S. Has a long tradition of sending poorly qualified people to the White House, but this is getting ridiculous. This guy the Republicans have chosen to run has managed to combine all the worst qualities of American politicians in one outrageous package.  The man has no qualifications to lead the nation in any direction other than backward, and possibly into chaos.  Just his hair should be a cue.  What are those people thinking?

I understand the discontent.  A lot of people are not liberal and want leadership addressing their problems.  Stagnant wages, a lack of good skilled industrial jobs, and rapid change rather than a safe, stable, comfortable life like Ward, June, Wally, and the Beav lived.  They forget that the Cleavers didn’t exist, they were just a TV show.

They sit in front of the TV watching pretty people having a crisis which always has a happy ending.  Their lives aren’t so happy, and they are angry about it.  So here comes a TV show host who says he can fix everything.  He will get rid of “those people”, give them good jobs, make the country safe, and put steak on the plate and a nice diesel Super Duty pickup in every driveway.  If there is trouble, the Marines can stop it.  The country will regress or else.

The mainstream Republican approach is to make rich people richer, take away benefits, and cut schools, highways, parks, sell the government land off. and send their sons off to endless wars.  Congress is paralyzed.  That plan has run its course.  The only reason it worked at all is the rich ones spent lots of money fooling people and buying politicians.

The result is Donald Trump.  He says he can fix it.  Well, no.  The man seems to have no idea how our government works.  He thinks he can issue commands on impulse and get an immediate response, whether his commands are legal or not.  The only things he really wants are adulation and a chance to get rid of those who ask the wrong questions.

Hillary has done a lot of things well, but she has a past.  Trump will sling as much dirt as he can, hoping enough will stick to her to get him elected.  It worked with the primaries,  let’s hope it won’t work for the Big One.

King Coal’s Crown is Slipping

Idle Coal Car

Idle Coal Car

Recently I have done a couple of road trips where I paralleled abandoned or seldom used railroads.  On one trip I came down the Arkansas from Salida to Pueblo, years ago the main line of the Denver and Rio Grande Railroad.  The other route was from Alamosa to Walsenburg, the route of the Rio Grande to the San Luis Valley and on to Gunnison over Marshall Pass.   

On both trips the lower portion of the railroad grade had literally miles of parked gondolas, or coal cars.  The gondolas on the Arkansas were the old-fashioned steel cars.  Those cars are replaced by mostly aluminum cars which are significantly lighter.  The railroads make more money hauling coal instead of heavy steel cars.  Dropping down to Walsenburg were miles of the more modern aluminum cars holding air rather than coal. 

The railroads have lost a huge amount of coal hauling business.  All over the country, coal mines are shutting down, the coal replaced by cheaper natural gas.  Not all the coal trains are gone, I saw one yesterday on its way south through Denver.   

Colorado Springs Power Plant With Idle Coal Cars

Colorado Springs Power Plant With Idle Coal Cars

Colorado Springs has a socialist Utilities Department, generating power and delivering natural gas along with the traditional water and wastewater systems. The big power plant south of the city used to burn so much coal the city bought its own coal train.  All those cars are idle, sitting at the power plant.  Now, it is natural gas powering the generators. 

Colorado has a colorful coal mining history.  The Colorado Fuel and Iron steel mill in Pueblo got its coal from mines just west of Trinidad.  That region had lots of mines accompanied by lots of labor trouble around the turn of the twentieth century.  There were mines in Colorado Springs, west of Denver, a big industry around Louisville and Lafayette.  The mines at Somerset, just north of Paonia are in the process of shutting down.  Craig and Hayden are in trouble, and the mines in the Grand Junction region are long gone. 

“Clean Coal”, a big lie if there ever was one, is on its way out.  Peabody Energy is bankrupt, along with many other mine operators.  We will have coal’s legacy for a long time.  Climate change, fouled rivers and air, areas mutilated by strip mining, and huge piles of mine waste are our children’s inheritance.   

wind_energyAlternative energy, including solar power and wind generation are part of the equation, but cheap and more clean burning natural gas is the main reason for the change.  Gas is cleaner than coal, but it still puts huge amounts of carbon into the atmosphere.  It is just another fossil fuel.  The fossil fuels sequestered huge amounts of carbon that otherwise would contribute to global warming.  Now we are burning all that carbon and heating up the planet. 

Gas is better, but still bad.  All that cheap cleaner burning gas may even slow the transition to renewable energy sources.  On balance, however, we are better off with gas than coal. 

Where is all that cheap gas coming from?  There has been a major technological advance in the oil and gas industry.  The advance is horizontal drilling.  In past years, one hole went into the ground and the oil and gas was extracted froze around that single hole.  The amount recovered was highly dependent on the porosity of the rock formation holding the oil and gas.   

Hydraulic fracturing (fracking), developed in the 1950’s expanded the amount removed from less porous strata, but not on a huge scale.  To get more out of any field with tight rock required lots of expensive drill holes.

The big change was the development of horizontal drilling.  The process took years of development, but now slant drilling is cost effective and allows hydraulic fracturing over a much wider area compared to down hole drilling.  Fracking the slanted holes allows gas and oil to be extracted from oil and gas bearing shales formerly not economically feasible. 

There is much opposition to fracking because the technology allows drilling in new areas where the population is not used to a dirty industry in their back yards.  Traditionally, the industry did not pay much attention to leaking wells.  There was little regulation, and all that stuff went into the atmosphere.  The oil fields in the Four Corners region are the source of the highest atmospheric methane readings in the country.  

Leaks are common because it costs money to prevent them, lowering profits.  The leaks can be prevented, it just takes more work and money.  The big blowout in the Gulf shows that oil companies tend to cheat when the dangerous practices are taking place where no one can see them.  On-site regulation can stop the cheating and oil and gas production from horizontal drilling and fracking can continue safely. 

The downside is the clear need to eliminate our dependency on fossil fuels.  We need to remove carbon from the atmosphere, not increase the amount.  Until more alternative sources come on line, natural gas is preferable to coal, and King Coal can be deposed.  The current difficulty in making the transition is political, with the extractive industries resisting the change at every step.  They are spending money to delay the changes that could be used to make change, not enrich politicians and the advertising industry. 

Residential Solar Power

Residential Solar Power

We have solar panels on our house and garage.  Out utility bill this month will be less than twenty dollars.  Xcel Energy is attempting to eliminate the incentives for home solar power so they can continue to produce power using natural gas.  It’s political, folks.

Cleaning the Water

Building The Marston Plant a While Back

Building The Marston Plant a While Back

I spent 30 years in the water treatment industry.  Most of it was water treatment, but I put in three years in as a wastewater treatment operator.  The goal of both jobs is to make dirty water clean.  The processes are different, and the standards for the product differ, but the idea is to make the water safe for humans.   I wouldn’t recommend drinking wastewater plant effluent, but you can swim in it.  Water, you can drink, except in Flint. 

What about the stuff taken out of the water in order to make it safe?  In both instances the stuff is called sludge.  Sludge is nasty.  There are several kinds of wastewater sludge, some nastier than others.  The first step takes out the stuff that sinks.  In a wastewater plant,  that stuff is the nastiest.  I once fell in a pit of primary sludge, injured a finger, and lost it to infection.  In Spanish, my nickname is Nueve.    

There are several techniques to deal with wastewater sludge to render it more benign, but it still tends to stink.  (By any other name, it’s still shit.).  That sludge ends up on farmland or as compost.  Water plant sludge is treated differently, but gets used the same way. 

Water Filters

Water Filters

I spent sixteen years with Denver Water in the Marston treatment plant.  It is fed by Marston Lake with water from the South Platte River.  Most of the time South Platte water is high quality Rocky Mountain water.  At other times, the Rockies get unruly and send some dirty stuff down.  The treatment plants have to handle it all.  Water treatment is known as a physical-chemical process.  A chemical, usually aluminum sulfate is added to the water to make bigger pieces out of the sometimes microscopic pieces that must be removed (bacteria, viruses, cysts, silt, etc.). 

Then, the water goes into a big tank where those bigger pieces tend to sink to the bottom.  Machinery of some sort scrapes the settled sludge out and sends it to be treated further. 

The settled water then goes to the filters where almost everything is removed.  Next step, chlorine to kill all the little nasties that make people sick.  Then it goes down the pipe to town. 

Sludge

Sludge

What about all the sludge?  Lots of things are in the lake water.  Birds, fish, even small organisms create waste products that can be dangerous as well as unpleasant (shit).  It is mostly water, but the solids have to be dealt with.  At Marston, it goes into a big underground tank and accumulates until it gets removed, dewatered, and hauled away for compost making. 

The tank is 20 feet deep, 50 feet wide, and about 150 feet long.  After accumulating for a year, the tank is about six feet deep with sludge.  Now, water plant sludge is not as nasty as wastewater sludge.  Some of it is chemical, clay minerals as the end product of all that aluminum sulfate.  But, there are lots of organics as well.  When they sit for much of a year in an airless environment, they decompose into stinky stuff.  That stinky stuff also gives off hydrogen sulfide gas (the rotten egg smell).  H2S and water make sulfuric acid, not good for lungs. 

To get rid of that huge gob of stuff, we had to get down there with fire hoses, air monitors, and gas masks.  Nasty work and a contrast with our normal routine of lab work, monitoring the computerized systems, and doing routine maintenance.  Dirty work with those hoses, but kind of fun as well. 

Belt Filter Press

Belt Filter Press

We used those hoses to carve sludge.  We would make channels, wash down walls of goo, bore holes, make it spatter our coworkers, and other exciting activities.  The whole process took a couple of days.  The sludge then went to a thickener eh are much of the water drained off the surface and the sludge drained out the bottom.  Then, on to the belt filter press.  That thing looks like a big printing press.  The sludge goes between two five foot wide belts that go over and under a succession of rollers that squeeze much of the water out.  The resulting cake goes up into big hoppers and then into trucks, and hauled to the compost making facility.  In the old days all that stuff went into the river.  Now, it is a useful product. Pretty cool, eh?

 

The Golden Fault

Red Rocks. on the Golden Fault

Red Rocks. on the Golden Fault

I live at the base of the Southern Rocky Mountains.  The Rockies are a lengthy mountain cordillera running from southern New Mexico to well into Canada; almost in mid-continent.  The most dramatic portion is in Colorado in terms of elevation and extent.   You may have heard of Pikes Peak, one of sixty three 14,000 feet high mountains.   

Usually mountain ranges sit at continental plate boundaries.  The Sierra Nevadas, the Cascades, the Andes, the San Gabriels, and the mountains in Central America are an example.  The Himalayas are the result of the Indian sub-continent colliding with Eurasia.  So, why are the Rockies here?  The most accepted theory is the Pacific tectonic plate once failed to subduct at the continental boundary and slid under the continent then dove, pushing the Rockies up.   

All the features of  mountain building are here, volcanos, lava flows, and a succession of mostly parallel ranges.  The anomaly is they are about 800 miles from the coast.  Our current Rockies are not the first ones here.  The 300 million year old Ancestral Rockies rose, wore away, and were replaced by our modern Rockies, about 64 million years old.  The idea is there is some sort of crustal weakness under the Rockies contributing to their birth here.   

The western Rockies sort of grade off onto the Colorado Plateau and the Basin and Range province.  On the east side, things are more dramatic.  Travelers go along the gradually rising Great Plains until wham, the Rockies poke up.  Flat country, than mountains.  Lots of us live along the base of the mountains.  There is water, good soil, nearby timber for building, and a dramatic setting with a somewhat better climate.   

The Native Americans often wintered here, returning to the plains in spring to hunt buffalo (Yes, buffalo, not bison. Leave that name for the biology geeks.).  The Pikes Peak gold rush meant the end for the Indians.  By 1870, the plains Indians were gone from Colorado.  The miners and the followers stayed, and the Front Range Urban Corridor grew to the crowded area we get stuck in traffic today.   

Just west of Denver is the Golden Fault. The big crack of the fault along the base of the mountains west of Denver dived westward under the mountains when the Rockies rose during the Laramide Orogeny, about 64-67 million years ago.  The uplift along the fault exposed rocks that are buried 14,000 feet down east of the fault.  The San Andreas Fault can’t match that one.  In addition, the mountains slid about one and a half miles over the plains.    

Red Rocks Park, home of many rock concerts, is composed of the Fountain Formation, about 300 million years old, formed of debris shed off the Ancestral Rockies.  Just to the west are what geologists call basement rocks, 1.7 billion years old.  The gap is the Great Unconformity, with the geologic record missing.  All that time is gone due to erosion.  Those basement rocks are highly modified remnants of an island arc which drifted north across an ancestral ocean and collided with the older rocks of the Wyoming Craton.  The same process is going on today as  the Phillipines, Java, Taiwan, and the other islands are headed to a collision with Asia.  Listen for the noise from the smash. 

Another benefit of the Golden Fault for us is all the interesting rocks tilted up by the fault.  Red Rocks, Dinosaur Ridge, Lookout Mountain, Green Mountain, and North and South Table mountains all owe their origin to the fault.  The last three are with us because of a lava flow originating from north of Ralston creek. 

Another fun feature is the erosion which wore the Rockies down at almost the rate they were uplifted.  The result was a gradual plain sloping off the mostly buried mountains to the prairie.  Then, Monument Creek, the South Platte, Clear Creek, the Big Thompson, and the Cache La Poudre, and their tributaries went to work, along with some more uplift.  The erosion created the canyon-carved escarpment we have today.  The Rocky Mountain Erosion Surface is the result of the river’s work.  From Green Mountain Falls to Estes park is a bench marking the ancient surface.  The Rampart Range road and the Peak to Peak highway run along the surface, with scenic canyons carved into the rock.  Deer Creek Canyon, Clear Creek Canyon, Golden Gate Canyon, and Coal Creek Canyon are some of the canyons we can drive down today.  Thank the South Platte River and Monument Creek for the scenery.   

The Laramide Orogeny uplifted the Rockies, with the now buried Golden Fault being a major feature and result of the bulging, and the later exhumation created the landscape those of us living on the foreland enjoy today.  The Rockies may still be rising, but it is slow compared to the coastal mountains.  The South Platte just keeps on digging. 

If you feel some shaking of the earth, it may be from the southern San Andreas fault letting go.  It is locked, but there is about 100 feet of movement between the Pacific and North American plates ready to happen.  Another earthquake source is the New Madrid Fault south of St. Louis.  As they say, it is not if they will move, but when.
