Isosceles

This is the Shacks' version of

Atari

at the Happy's!! Looks classic, climbs okay. Isosceles ascends the triangular-looking south face that is obvious from the parking lot.

Start by liebacking and heelhooking the right arete until it is possible to reach out left and sidepull the left arete. Do some cool double sidepulls until a committing throw to the apex (good). Mantle straight up over the south face (don't escape out right).

This is on the Ridge, look for big, triangle-shaped face.

A very GOOD spotter, if you fall you risk bouncing off the ledge and falling even further down left into talus, especially if your heel hook blows.
