In Sierra Vista, Arizona, off of Highway 92, there is a mountain range
named Carr Canyon. Near the base of the mountain (not far past where
the homes are) is a mysterious place we call "The Mansion", for lack
of knowing what is was really called. We suspect it burned down many
years ago (at least pre 1991, presumably many, many years before
then). You can clearly see pipes where plumbing was, and there are
several names written in the once fresh concrete (I don't remember the
names, but beside one of the names was a date of 1950 something or
other). The place was made of stone, had a fireplace (there are stairs
leading right up to the fireplace, which now has a tree growing out of
the top of it), and a 2 port garage or 2 bedrooms, which are directly
connected. Part of it was painted blue, and the ground (which is made
of concrete or stone) is maroon. Also, there are several various
engravings in the stone itself in various places. One of the
engravings appears to be a square with an X or a / running through the
middle. I do not recall the other engravings. However, one of my
friends stated he thought one was possibly a military symbol of some
sort (note that Carr Canyon is in a town that neighbors the military
base Fort Huachuca).

My question is simply this: what was the purpose of this place, and
did it in fact burn down as we suspect?
