Around the corner to the right lies a big slab which has several popular moderate routes, including Incline Club (8), Tomb of Sorrows (9), and Disinclination (7).

Getting There 

Climb up the talus field above the Tyrolean Traverse. A dirt path starts at the top of the talus. Follow the path uphill a bit until the trail splits. Continue up the hill on the right trail branch. You'll eventually reach a steep wall with a scooped-out face; this is the route Strange Science. Free Fall is the arete to the right. The slab routes Disinclination and Incline Club start just up the hill to the right, at a right-facing corner. Tomb of Sorrows starts at the top of the slab in a chimney on the left.
