Phobos/Deimos Cliff Rock Climbing
BETA PHOTO: Phobos/Diemos Cliff
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
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.

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).
