I'll dig this one up from the archives. What a great area to ride. The RR in my sig line has some of the same areas you rode. Beaty's butte us a must ride if you're in the area. Looks like you missed Cavespring at the bottom of the butte. Way cool place to refill on water.
On another ride in that area, my cousin rode the trail west out of Shirk ranch towards Hart mtn. on his loaded F800GS after a very long day. The ride to the top was wicked difficult for him be he made it. He must have gotten bounced of the trail a half dozen times. We were trying to reach the hot springs to camp for the evening but by sunset were still too far away and way to tired to keep riding so we just stopped and pitched camp right in the middle of the rocky trail. Slept....like a rock.
Thought I'd give this a little bump back to the top!
