This warm, south-facing cliff band is home to a few steep, classic crack climbs. These include Phobos (5.9+), Deimos (5.9+), Blues Riff (5.11b/c) and Goldfinger (5.12a).

Getting There 

The cliff sits just east of Tenaya Lake and the huge Moutaineer's/Harlequin Dome complex. It is directly across from Pywiak Dome. Parking can be found directly below the dome at a small pulloff, or in the main Tenaya Lake parking lot.

The approach up to the cliff is a grunt. The trail is well-marked however. Allow 45 minutes.

The counterpart to Phobos, and the other namesake climb of this cliff, Deimos is an excellent steep climb with a lot of hands/fists/OW crack. It has a bit of a reputation as being hard, burly, and with less than perfect protection. I found none of these to be particularly true. The climb is truly a bit atypical for Tuolumne, being more reminiscent of Valley crack climbs with lots of wideness and flares. But after the first 30 feet, the rock is excellent, there is pro wherever you want it, an...[more]   Browse More Classics in CA

Cordelette on the top rappel station is very worn (sheath cut through by bolts) so I added a piece of sterling power cord to the mix. I didn't have a knife, so wasn't able to cut down the old cord and re-knot mine. Feel free to cut away the old stuff/retro mine; even better if you can equip the station with mallions. Added some webbing to the bottom rappel station as well, so the entire descent should be in good condition.

Bottom rappel is a slung horn directly below the top rappel at ~63 meters. I made it with less than a meter to spare after rope stretch. Alternative is swinging left to Blues Riff's anchor (assuming nobody is on route).
