See Mick Schein's Sandia Rock guide for a complete description.
A hidden area with clean steep faces. These areas consist of a few easier trad climbs along with some harder mixed climbs. Consists of two different levels, Science Friction being the upper wall and Windward wall being the lower wall.
Windward Wall: Blender Head 5.7+ Leftist Tendoncies 5.9 Storm Warning 5.11d Good Clean Fun 5.11a The Windward Passage 5.9+ Sea Breeze 5.9
Getting There: Science Friction Wall
Approach from the crest from the crest spur trail to the junction with the La Luz. At the junction head west (towards Albuquerque) on a primitive climber trail head up to the ridge above Echo Canyon.
Follow the ridge first south then west until you reach the cliffband. You will pass several don't disturb boundary marker signs on the way. Locate a pair of rap anchors (tough to spot) and do a 150' rappel down A Face Odyssey to the base of Science Friction Wall. There is a huge bolt halfway down which you might be able to stop and do a second rappel if needed.
Getting There: Windward Wall
Once at the base of Science Friction Wall, Scramble uphill North through woods to the base of Pub Draught Guinness. Head west to the top of Windward Wall and rappel Good Clean Fun in 1 double rope rappel or 2 single rope rappels to the base of the crag.
Mick's Sandia guide also mentions that it is possible to approach by hiking down the La Luz to The Fin, hike up talus opposite the Fin, the scramble east to the base of Windward Wall.
Start by the tree with a hand crack coming off the ledge, lieback and face climb to the roof, pull the roof move (careful of the blocks on the right they are loose) and follow bolts to ledge and cold shut. 2nd pitch (you can link the 2) follow bolts up through seams and grooves to rap bolt anchor....[more]Browse More Classics in NM
Rapping Windward Wall in two single rope rappels: watch the rope ends on the last rappel; a single 60 meter won't reach the dirt; but - for us - it did reach a ledge a little off to climber's right (easy 15 foot down climb from this ledge).
