I made this terrain a couple weeks ago by using USGS terrain data of Camelback Mountain near Phoenix, AZ. I lived for a while in the Phoenix area and I think it so cool that I can have a virtual representation of one of my favorite geological formations. BTW this is one of my OS Grid regions. This is NOT something you can do in that other large MMPORG place.
But the really good news is you CAN do it either on your own computer or on the OS Grid using the Open Simulator software.
