There seem to be increased readers on weekends, so likely I will begin planning my posts for the weekend, or Thursday through Monday or who knows where my mind goes? Oh, the lyrics were actually “Who knows where the time goes?”
Looking back through my collected vacation literature I was delighted to see the National Park Service called Bryce Canyon “Poetry in Stone.” No, I did not write poetry about it, just tried to capture the grandeur in photos!
From Bryce we did make it that night to our motel in Cedar City. I want to back track to Capitol Reef, where we so enjoyed the scenic drive through the many geological features. One thing I did not emphasis was the black rocks.
The Park Service describes these as coming from 20 to 25 million year old lava flows. “Pieces of lava rock were transported many miles from their source, and were smoothed and rounded by their violent journeys within gritty floodwaters. When floods receded, black boulders were left scattered across the floodplains. The black boulders are black on the inside too! The white coating on the surface of many of the boulders is a mineral crust known as caliche, which is mainly a thin film of calcite and gypsum crystals. Caliche forms when mineral-laden groundwater seeps upward, coats the underside of the boulders, and evaporates from the surface, leaving its dissolved minerals behind.” I found the white frosting on the rocks as interesting as the rocks themselves.
I just find this stuff so interesting! Reading National Park literature I can learn a bunch without having to study geology to discover the facts. Nice they teach me as they publish!
I kept thinking of my baseball friend, Levi, and wanting to pick up the baseball sized black rocks. But alas, I am too honest, and could not do it. Besides the Park Service asked us to “not disturb or collect rocks or other park resources.”
I did pick up a smaller black rock along the side of the road after we left the park. Alas, neither one of us took a photo of the large black boulders 🙁 So you will have to imagine!
