Remember
the joy a great dirt pile or a big sand box provided you as a kid? As youngsters, my brother and I would spend
hours creating our own geography which included mountain ranges, deep valleys,
sloping hills, and raging rivers. All we
needed was dirt or sand, a couple of spoons or small garden shovels, and water.
As
we grew more sophisticated in our play, we mastered road and bridge building
and added our collection of toy cars and trucks and, eventually, army men to
the worlds we built. Without knowing it,
we learned a bit about geology.
With
the hose or a bucket of water we could create torrential rain storms which wore
down our mountains in no time, leaving our army men exposed on flat
plains. We could create bodies of water
that ate away vast canyons equal in scale to the Grand Canyon . Mud slides became an art--we could take out
the other guy’s army, leaving tiny green men and their jeeps buried neck deep
in mud. What power!
Using
compression, we generated mountain ranges which complicated the other person’s
road and bridge building. By mixing vinegar and baking soda together in a
crater atop our mountain we could simulate volcanic activity. Sixth grade science class opened new doors to
our creativity.
Within
our backyard we recreated the universe, and, at the same time, created an
everlasting curiosity about geology in both of us. To this day, the theory of plate tectonics
intrigues me.
What
interests me more is the idea that geologists can trace rocks and minerals from
our plains to great clefts in the Rocky Mountains . Yes, some dirt in Kansas
is really old, old Colorado
dirt. I suppose that is how trace
elements of gold ended up in the Smoky Hill River, leading early speculators to
believe Kansas
would be the site of the next gold rush.
That
brings me to my next wonderment. We
recently traveled to southwest Wyoming and
visited Fossil Butte National Monument . In itself, it looks like a barren chunk of
earth rising from a sage brush plain that looks much like parts of western Kansas . It runs north and south with gentle east-west
meanderings for miles along the western Wyoming
border. What makes it special is the
fact that it is one of the richest fossil fish sources in the world.
At
one time, this area was part of a great inland sea. What interests me is that you don’t find the
fossil fish at the base of the buttes; you find them toward the top. This didn’t make sense to me. Wouldn’t gravity pull all those dead fish
down?
When
I inquired about this, the park guide explained that the top of the buttes
actually represents what had been the bottom of the sea. So... what was the bottom of the sea is
actually higher than the present surrounding area. Erosion had done astounding
work, eating away huge amounts of rock and soil, leaving me to wonder where all
that dirt went.
In
my mind, I try to imagine a cosmic sand pile.
Even with my greatest imaginary powers, I can’t fathom how that much
dirt shifted from one place to another. What kind of force could move so much soil? Would the United State
have been a much taller yet narrower country if that dirt had not washed
away? How long did it take? Where did it actually go?
Geologists
have the answers to my questions, but I have a lot of fun imagining a huge
cosmic sand pile formed by a Creator having a great time. I know that I certainly enjoyed my turn as
creator in my own sand pile.
