Long Mountain by Dan Saxton

Elevation: 10,728 ft
Prominence: 708

Climbing and access information for this Lemhi Range peak, one of four Idaho peaks named Long Mountain, is on Page 297 of the book. 


This expands upon the information in the book. Long Mountain can be attained fairly easy from its East and South ridges. I did it as part of a backpack trip in the Hayden Creek Valley along with May Mountain.

To climb from the south, try to find a stable route up the scree from the lakes south of Peak 10402. Once atop the ridge, excellent goat trails lead you up over Point 10402 and Point 10442 onto huge tundra flats before ascending Long Mountain’s west peak (which has the name on the topo map) and then turning east to the main summit.

To climb from the East Ridge, leave the Hayden Creek/Kadletz Creek trails at the highest point on the ridge and follow the ridge to the top over scree and talus. No need to climb on snow, as the book says. USGS May Mountain
