Today I present to you the "coral pink sand dunes" from southern Utah! (At least 2 square kilometers are definitely there)
There is a southern part of the dunes with some vegetation and steeper cliffs on the hills to the east.
There is a closed-circle racing track in the center of the map. The layout is based on one of the longer Texplex courses.
Overcoming all the dunes is an 11-kilometer route.
There are dozens of kilometers of trails in the mountains to explore, which I have arranged so that they are something like a maze to make the trails seem longer than they actually are.
All trails and courses are numbered. Not that I think AI can handle them all, but so that you can see the paths in the navigator.

In version 1.3.2:
This update is designed to solve the problem with missing textures. It looks like I had a cache conflict with one of my other maps last time, which caused the textures to overwrite these.
