Precious Lost and Sumatra are two new routes on the shady side of Little Cottonwood Canyon. Both routes are fun, adventurous, not very sustained and consist mostly of slab and crack climbing. Cruxes are short and well protected. Because these routes are new, and are not included in the current local guidebook, they are rarely crowded. If you liked the last pitch of Pentapitch, you will certainly enjoy the position that these routes offer. Both routes share the same first pitch, and go through a dirty, low angle 2nd pitch. Expect some loose rock and dirty sections.

Precious Lost is the longer route of the two and offers a lot of variety and quality moves. The highlights on this route are several great slab moves, a widening crack on the 3rd pitch, a roof crux on the 5th pitch and an exposed finish over flakes on the last pitch. Overall, Precious Lost is not sustained and feels more like a 5.9 with a few moves of 5.10. The protection is good with a variety of bolts and natural pro.

Sumatra is located just to the left of Precious Lost, and branches out left on the second pitch. It then takes you up a very fun slab and dike crux section on the 3rd pitch, which is the highlight of the route. Both the 1st and 3rd pitches are really fun, with clean rock and excellent climbing. However, pitches 2 and 4 are lower angle and a little more dirty. The rock and pro are mostly good and the moves and position are excellent.

CAUTION: These are relatively new routes, and there is still some loose rock. Be extremely careful with loose blocks, as rockfall potential is a real issue in this area. If a party is already on the route, consider something else and avoid hanging out at the base.
