If you go exploring out there, use caution. Death Valley itself has it's share of danger. Top that off with the border not being clearly marked and
security from China Lake apparently very diligent.
I've seen that before on GE and looked it up and came across the same post. It is very interesting. Oddly enough that's one thing I never heard
about in my time in Ridgecrest.
If you play with the history tab, going back one step gets a new image. Probably a bug in GE. You see more structures on the newer imagery, so the
place is quite dynamic.
