Hey Old Dog, I have read about a person named Mandel Torres,who in 1940, discovered a covered mine shaft near the summet of Culebra Peak, and traveled through it about 300ft. A part of the story states in so many words the shaft may pre-date Spanish explorers,and work tools may have been found inside. Since this is your neighborhood, I thought you might be interested....HH
PLL, I believe I Have seen what I believe are Spanish Pointers in Calif.desert,at least 1 being close to Borax,Calif.
I dont have gps imformation on them,as you know the desert is a wiley place and landmarks have a tendency to appear and vanish..... HH
