Peak 10743 is located on the Iron Divide, a prominent ridge line that separates the South Fork Big Creek from the Big Gulch drainage. This ridge line is west of the main Lemhi Range Crest. It includes three other ranked Lemhi summits on its ridge crest: Bear Mountain (10,744 feet), Iron Creek Point (10,736 feet) and Peak 10592. USGS Big Creek Peak

South Ridge, Class 2

Date of Climb: July 14, 2019


Big Gulch Road/FSR-099 [(C)(5) on Page 317]. Big Gulch Road is located along the Pahsimeroi Highway about a mile N of Summit Reservoir and exactly 6.6 miles S of the major road junction in Goldburg. Drive 2.0 miles up FSR-099 to the Challis National Forest boundary and park (7,180 feet). USGS Big Creek Peak

The Climb

From the parking area, begin a 2-mile cross-country trek to reach the base of the South Ridge at the 4th creek crossing W of Big Gulch Road. Follow a fence row N from the Challis NF boundary down to Big Gulch Creek. Cross the creek about 100 feet upstream from the cattle fence in a willow-clogged area. Return to the fence row and follow it N then NW until it ends. From that point, contour NW through sagebrush to reach the final, 4th creek/stream crossing. Once across this final stream, you are at the base of the South Ridge (7,850 feet).

Bushwhack NNW up through forested terrain with lots of blowdown and a base of loose scree/gravel. The South Ridge is ill-defined at first, but soon becomes very well-defined and easy to follow. The slope eases a bit and the ridge crest has less blowdown and more stable scree/gravel. There are no rocky outcrops to contend with. Reach a flattish ridge area near Point 9921. Once past Point 9921, the ridge temporarily heads R-ish/NE and drops about 25 vertical feet to a minor saddle.

From the saddle, scramble NNE then N up the steepening ridge. The forest is open here and isn’t too bad. Reach tree line about 300 vertical feet from the summit. The terrain above tree line is a combination of talus and scree and is a bit loose, but not too awful. The South Ridge reaches the summit ridge about 0.2 miles W of the summit. An easy stroll E on the summit ridge on flat talus/scree brings you to the summit of Peak 10743. The summit has a nice cairn atop the high point.

Northwest Ridge (Descent), Class 2


Same as for the South Ridge Route

The Descent

From the summit, follow the ridge W then NW for about 0.7 miles to the 10,020-foot connecting saddle with Peak 10592, dropping over 700 vertical feet on the way. The terrain on the Northwest Ridge is a combination of talus/scree (mostly) and some ridge crest pines (and blowdown) to slow you down. You will find goat trails to help circumvent some of the ridge crest issues. The ridge crest pines do block the west wind if you stay on the R/NE side of the ridge crest. There are a few ups and downs along the way, but nothing too tedious.
