What you are looking at is a portion of the Carson Sink, east of Lake Tahoe.
Looks like a playa...very flat, large, intermittently wet. The "vines" you are seeing is a normal erosional feature. It has a dendritic stream
Where the tire tracks aooear to go under the vines, the vehicle, probably travelled through running water.
The overall color is reflected in the playa bed. It is very "salty" in character, giving rise to the color.
There is a test range in the center of the "sink".
