Peak 10055 is a ranked summit and is the high point on a long, meandering ridge between Timber Creek Pass and Flatiron Mountain. Its North Ridge separates Squirrel Creek from Cabin Creek. Peak 10055 sits in the shadow of massive Flatiron Mountain (11,019 feet) to its west. It is, in actuality, the final ridge point on the East Ridge of Flatiron Mountain. USGS Iron Creek Point

Southeast Ridge, Class 2+

Date of Climb: July 12, 2019

Access

Same as for the Southeast Ridge of Peak 9727. This route is the final leg of a ridge traverse from Peak 9620 to Peak 10055.

The Climb

From the 9,300-foot connecting saddle with Peak 9620, follow the Ridge Trail/FST-4076 SW up to a ridge hump. Leave FST-4076 here and follow a good use trail along the ridge crest SW then W to the top of Point 9789. Point 9789 is a ridge corner. It joins the primary East-to-West Ridge with a ridge heading South (which FST-4076 follows). There is a large cairn atop Point 9789. The ridge traverse NW from Point 9789 to Peak 10055 is straightforward and has a good elk trail near the ridge crest in many sections.

The ridge terrain is a mix of open scrub/grass, scree/gravel, ridge rock, and short stretches of pine forest. The summit ridge rock is the only section that is Class 2+. The ridge does have its ups and downs, including an initial 200 vertical foot drop from Point 9789 to a narrow saddle. The traverse takes about 40-45 minutes to complete. The summit of Peak 10055 has a large cairn. There are a few more cairns, no doubt placed by hunters, on the Southeast Ridge of Peak 10055.

The Descent

From the summit of Peak 10055, descend the Southeast Ridge back to the 9,300-foot connecting saddle. From there, follow the Slide Creek Trail (a MC trail) down to a [signed] junction with the Timber Creek Trail/FST-4137. Follow FST-4137 back to FSR-105 and your parked vehicle.
