I think those are layers if it is in the location I believe you are showing.

Those are ditches put in to control erosion and reduce flash flooding down hill from those peaks. My grandfather used to put those in with a bulldozer working for the Forest Service. He might have even put in those very ones (can recognize the mountain from the pictures, looking at the other side of it out my window now).

Less certain about these, but I think those are ant hills. The ants clear out the vegetation for a bit around the nest, you sometimes end up with a ring of extra grass/brush at the edge from the extra water. Regularly see similar when walking in the great basin parts of Utah.

Sure does look like water bars to me, we used to do them after a fire.

Circles are where the worms come out to feed on hapless downed pilots. Be sure to bring dynamite / satchel charges and a damsel to be in distress at the right moment.

Reminds me of a "Boil" that would happen near a levee when there was river flooding.

Being an old(er) glider pilot, Id be circling in a heartbeat to get free gas (altitude) especially in the 9 with 10 degrees of flaps at idle!
