Thanks for that great information. We are planning a trip there in May. I will cross check our planned tracks against the OPs tracks and your information. I think all of my tracks are based on actual rides by others.
BTW. I am really intrigued by Red Rock Rider's exploits. I have done a little riding in that area and we will be going thru there in May.
During the cold last winter I created Garmin routes as best I could of a lot of his rides from looking at the Benchmark maps he posted.
I don't want to post the file since I am not sure of its accuracy. But if anyone PMs me, I will be happy to send a copy.
