strange, I could swear it was a higher altitude, was this made in the summer?
No. Actually I was there two weeks ago today. It is just below Baylor Pass and directly above White Sands Proving Grounds. The altitude my be some higher than that but not much. It certainly isn't high altitude like we think of here.
I began thinking about the elevation of Aguirre Springs so I checked Google Earth. It shows the elevation as 5289 ft. I knew that White Sands N.M. was about 3000 so it didn't seem that it should be very high.
