Flatiron Mountain is the 122nd-highest Idaho peak. It often climbed in conjunction with nearby Big Creek Peak via a strenous scramble along the connecting ridge. USGS Big Creek Peak
Northwest Ridge, Class 2+ by Livingston Douglas
Date of Climb: July 18, 2014
FST-075/North Fork Big Creek Trail [(C)(4)(a) on Page 317]. I climbed the West Ridge Route on Big Creek Peak then descended the Southeast Ridge Route on Big Creek Peak to reach the Big Creek Peak/Flatiron Mountain saddle at 10,500 feet.
From the narrow, rocky Big Creek Peak/Flatiron Mountain saddle at 10,500 feet, scramble southeast up the ridge on mostly scree. You will find a goat trail on the ridge crest that will help you to some degree. The Southwest Side of the ridge is more docile than the Northeast Side of the ridge. The USGS map makes this ridge look much steeper than it actually is. It’s only marginally steeper than the Class 2 Southeast Ridge of Big Creek Peak. The summit of Flatiron Mountain has a gold USGS BM in a ground boulder. The peak has nasty exposure on its north and west aspects.
