this massive freestanding "boulder" is easily recognized as there is nothing else quite like it around. Shady most of the day with noon to dusk being the best (if its chilly outside expect to it to be more so here). rock quality is good with areas of choss (nothing big though just small pebbles and rock dust).

Getting There

upon getting to the Mecca follow the right "trail" (goes through the boulder field) staying on the inside of the fin.

This place had the best climbing I did in 4 days at tensleep. If you go to tensleep... go here! Aug 12, 2011

I hate to be negative, but his was my least favorite wall that I visited in Ten Sleep. The lines are fun but the rock is chossier and dirtier than other areas, resembling mud more than amazing dolomite. In addition some of the holds seemed a bit questionable making this less of a destination than Slavery Wall, Supererratic, and FCR. Aug 17, 2011

I'm with Phil. DTP, I agree that it could be considered a bit dirtier I think that's just because people avoid the confusing hike back there. The Joy of Heresy and Last Starfighter are 2 of the most elegant lines I have done period. We were the only party out there on a Saturday last summer, it has such a different feel than the rest of the canyon. Aug 17, 2011

The rock might look kind of chossy but it feels bomber to me. Absolutely worth the hike to get away from folks on the weekend--the formation is really cool looking and the routes are very aesthetic, imo. They have good movement to back up their looks, as well! Sep 15, 2012

We showed up early and the gate at the top of the old road was closed and the old road cut off. We cut a new trail starting at the first gate, hopping the barb wire fence, over the meadow and then an easy hike up traversing the big hill. Joins where the trail goes into the woods. It takes about 40min at a leasurly pace. I much prefer this to the slog described in the guidebook. Jul 7, 2017

Much thanks to beccs and the others who busted the new approach in. It rocks. Thanks for the quality new contributions at the crag! Jul 17, 2017
So, the Ark...

1 - The approach is fine IMO (used the guidebook one). Trail is on & off until you get in the wood, more or less. The cattle pound is relatively easy to find just by going up the open fields in the general direction of the cliff. Some cairns can be found there & eventually it leads to the wood. Once in the wood the trail was easy to find - better defined, cairns, cut logs etc... The approach is long but not hard. Not as straightforward as FCR, Mondo etc... but if you prepare a bit before going it needs not be an epic either.

2 - The rock is slightly different from most of what is in TS - it is less grippy (and not as sharp!) as other area. As for claims of choss/dust.... It depends what you are looking for. There are more pebbles/dust than elsewhere in TS. However it doesn't really detract of the quality of the climbs. Dubiuous rock is easily avoided and the actual holds aren't really all that dusty - if you don't focus on that there is awesome climbing to be had. If perfectly clean rock is desired, well then it's true it's not like Slavery... but then not as polished (or chalked) either.

3 - The climbs are long, the setting is impressive, you can easily find nice boulders for non-buttshot pictures and the temperature is much cooler than elsewhere in the canyon. Hiking out at sunset will reward you with an amazing view (though we missed most of it and hiked out at dark).

I would totally go back. A great crack for 10/11/easy 12s. Jul 12, 2018
