This non-motorized trail is the original Twelvemile Forest Service trail. It is raw, wild and five miles of pure fun for the expert mtn biker.

There will be short hike a bike for some bikers. There are numerous stream crossings, 12 crossings from top to bottom. Some crossings with logs...6 crossings between Second Crevice Bailout Trail and the Access Rd. Expect to get your feet wet. Early in the season, the water is high and cold.

Lower down you will pass a cabin site from the Uncle Sam Mine, which was operational before 1927. June-October is best. This trail is in the Twelvemile Grazing Allotment - expect cows from mid-July through September. Please close the gate during grazing season.

      Trail is clear other than the easy step over and the leaner mentioned in the previous report which is easy to get under.

      Large chainsaw worthy tree across road bed portion of Crevice. Another leaner tree just below this.

      This is a terrible trail. It’s like someone had an idea for a good trail and went and rode it a few times. Then they figured other people riding it would make it a proper trail (it does not, nor could most other people follow the “trail” given the complete lack of any signs and substantial bushwhacking required).

      So here's the deal with this trail (as of July 2020): From the top, down to the "Second Crevice Bailout Trail", it is absolutely fantastic- one of my favorite pieces of trail anywhere. Between the "Second Crevice Bailout Trail" and the "Access Road" ~a mile down-canyon, it deteriorates into a complete bushwhack nightmare. The best way to enjoy this is park at the top of the Second Bailout, ride the road to the top, then descend the trail to the Second Bailout and... BAIL OUT.

      Lower 2.8 miles cleared on 10-30-18. Couple big down logs yet but easy to step over.

      If you want to run into cows and go on a cow trail, then this is your jam. Expect to get your feet Poopie.

      Crevice trail has been cleared from top to bottom. Creek is high and crossings are treacherous this early in the season due to high water. 5/27/3018.
