Google Earth Find: Who Did This in the Desert?

Another interesting Google Earth find! My research associate, James Carroll, found this one when studying the California desert for signs of the supposed beached ship.

Being curious by nature, I had to look it up and found out that someone(s) really were leaving a nice sign for the Marine Fighter Attack Squadron 115. 

Did they put it out there (with great effort, as the letters are about 15-feet long and fairly wide), or did they hope to have the boys see it from the air as they flew over?

I don't know, but I find it pretty cool!
