I attached GPX files for a couple more loops that are not as long as the Cabin Under the Rock loop. The Cabin Under the Rock loop is 93 miles, not 73 miles as reported in an earlier post.
The first route runs northeast from camp and passes Muller Mountain and Table Mountain. It is 31.5 miles with about 4,200′ of climbing:
The second route runs southwest from camp and passes Pilot Peak and Thunder Mountain. It is 42.6 miles with about 7,700′ of climbing.
I haven’t ridden anywhere near Mina but the distance and scenery for these routes should be about right.
