This route ascends the westernmost rib of rock that rises out of Bear Canyon and leads north to the south side of Dinosaur Rock. This rib dies out near the saddle west of Dinosaur Rock, if you want to reach the summit you should continue via the West Face route (or South Ramps route).
The start of the rib lies between Bear Creek Spire and the Southern Dinosaur Egg. The bottom of the rib may be identified by a steep 30 foot high face at the bottom. Start right of this face and head up the rib.
About half way up, you will be stopped by a 20' vertical step in the ridge. One can climb straight up the crest at exposed 5.3 (watch for loose rock). A cowardly variation here climbs a fir tree right of the crest and is not recommended. After this you will soon reach on a small, keyhole shaped false summit. This is bypassed by downclimbing a bit and doing a short traverse on the east side. After this you will climb right over a small arch, although this is hard to see when you are going over it. Continue up to the saddle west of Dinosaur Rock.
Standard Flatiron rack.
