The Northeast face is somewhat broken and features a number of popular 1 and 2 pitch easy to moderate climbs. These include Bisk (5.4); Blistering (5.5); Wandering Tortoise (5.3); Easy Day (5.4) and Luminous Breast (5.8).
The South face lies in a sheltered corridor and is generally overhanging, with rock that ranges from good to poor. All routes are hard (5.12 to 5.14) sport routes. Satanic Mechanic (5.12a/b) and Desert Shield (5.13a) are the best known and most sought after routes. Integrity (5.14a) is the hardest route on this wall, involving a long traversing section.
