Another interesting outcrop from the Death Valley region. Ideas on the formation of the unusual pattern of deposition or emplacement? It is in one of the more remote parts of the park for those whose idea of "remote" means the end of the pavement without a return loop drive. The best clue I can think of is: is this outcrop
igneous or
sedimentary? Below is another view of related outcrops nearby.
Y'all have a restful weekend. I am taking our Geology Club on a caving expeditition in the Sierra Nevada foothills tomorrow.

I'll step out on a limb and put in a vote for both - possibly an air-fall tuff (basaltic?) component in some kind of sedimentary deposit. Can I hedge my bet any better?
ReplyDeleteMy vote is for the tephra layers at Ubehebe Crater.
