The first big wall after the fork which is directly in front of heatwave. Heatwave is the shady side (right) where as Catamount is the sunny side (left) as you walk into the canyon.

The easiest way to know which wall you're at is that catamount has really steep cave routes that are short in nature on the right side (Cave side). On the left you have more vertical on big holds or crimps.

Allow for about 40 minutes of hiking into the canyon
