Little Alien Face on New Mexico Topo Map

The UFO Museum in Roswell had a map that showed where the alleged crash sites were located. Now that I am back home, I checked out the Jim Ragsdale alleged crash site location on the topo map and noticed a little alien face placed near the site. Not a big deal, but it's funny what you can find on maps sometimes. For those not too familiar with the Ragsdale story, I provided some links.

Now to the pictures. The first one is the marker for the location. The second is the topo map. I x'd the site with a pencil and circled the area.




I wonder who put this on there and why? Funny though.

Sorry, forgot about the size.
This little face is pretty small, about 1/16th of an inch by 1/8th of an inch.
