These are exposed on the road leading in to Death Valley from the Panamint Valley to the west. That’s all I’ve got time for today, folks – gotta get to work.

Annotated version: Recall there are more chert … Read more
A few shots from Fossil Falls, in the southern Owens Valley, California… This is the now-dry river bed of the Owens River. There’s abundant evidence of water-induced erosion (potholes, polishing, etc.), but nary a drop of water to be seen – Though this particular portion of the Owens River drainage dried up in the Pleistocene, … Read more
