Wyoming '99: Monday
The valley surrounding the trestle was incredibly lush. Wyoming had been enjoying a healthy amount of precipitation when we visited. Often this grass might all be golden instead of green.
With Dale Creek running through it, of course, the valley has better odds of staying green than the hilltops around it.
Meanwhile, the valley is surrounded by stark (and beautiful) rocks. Again, geologists say much of the erosion of these rocks is done by the wind. True, there will be snow here in the winter, and when it melts every spring, the water runs off over the rocks. But the wind blows year-round, and it carries fine particles of everything in it (particularly bits of grit from the rocks it just finished eroding a few miles back), scouring the rocks till they're rounded like stones at a seashore.
Of course, in the sands of time, all these rocks once were under a mighty sea.
One way or another, they're not too hard on the eyes today.
