This is taken in the midst of the Great Sand Dunes of Death Valley National Park. I found the mesquite trees fascinating. Here is one atop a dune with the purple/blue/grey of a mountain looming in the background.

Late Update: just heard that the testing of the Oliver is underway. Thermostat failed and is to be replaced in the AM with a new one. It has been fussy for a while and this is not surprising. The good news is that they have moved from repair to testing. Yay!
