Here’s that mesa I found. I have been exploring the area and it seems like a good place for a wild-west themed wilderness. The coordinates of the area are -13340 88 8215.
What do you think of this? Personally, I think a wild-west town themed wilderness would be awesome and a lot more interesting than the other wildernesses that have been around.
Here it is on the map:

As you can see, the area isn’t completely untouched but it seems to be a good spot for a wilderness.
