Wed Jul 10 2013 Eagle Butte Mine

Wed Jul 10 2013

Eagle Butte Mine open pit "truck and shovel"
coal mine, in Gillette, Wyoming.



They just have to blast, push or shovel a layer
of about 200 ft of 'dirt' (the light gray layer
on top), and then truck out the black layer of
about 100 ft of 'low sulfur' coal.




After removing the coal, the landscape is
restored, re-seeded, just 100 feet lower.
And quite some wildlife can be seen around.

99 % of the coal is then transported on mile
long trains to power plants all of the US.

The guide, was a women who had been driving
one of these 12 ft wheel trucks.
Not much discussion about environmental points
about coal plants, by lack of any numbers.
And the remark that there is one who wants
to shut done all the plants, says again something.

These trucks are large, 240 tons in one go
is quite something. Check out the size of the
guy, compared to the wheels.





Next stop, Devils Tower.
An amazing volcanic eruption created this hard
stulp, 2 miles under the surface. And millions
of years of erosion, shows now the top 1000 feet.
The lines, like a bear claw is scratching the rock,
is the sudden cool down of lava in hexa-diagonal tubes,
as a hard compact maze.
A home to the real expert rock climbers.
Up to you, to find out about the sacred crap.
