Idaho mountains that rise higher than 11,000 feet above sea level are spread throughout seven mountain ranges in the south-central part of the state. With the Sawtooth Range to the west, and the Greater Yellowstone area just to the east, these ranges have been largely overlooked by the crowds. Just north of the area lies the Frank Church - River of No Return Wilderness Area, but most of these high peaks are largely unprotected.
Some of these summits are unclimbed, and most have only been climbed a handful of times. No one has yet claimed to have summited them all. Most of these peaks are rugged and provide a challenging ascent on even their least difficult routes. Anyone looking for a great alpine wilderness experience will easily find it on any of these peaks.
This page is meant to bring together the mountain pages that have been created on Summitpost. Only a small part of all of the Idaho Eleveners has had a mountain page created and submitted to Summitpost. To see a complete list of these peaks, including those that have not been posted here, see the Idaho's Highest Peaks page.
The region and mountain ranges are bounded by ID-75 on the west and north,which provides access to the Pioneers, Boulders, and White Clouds. US-93 follows the western base of the Lost River Range, and also provides access to the White Knobs and Pioneers. ID-28 runs between the Lemhi and Beaverhead Ranges. Mostly unpaved but important access roads are Trail Creek Road and the Little Lost River Highway.
More services are available in Twin Falls and Idaho Falls, a bit further from the peaks, but one will probably pass through these cities en route to the region.
Lost River Range
Long and parallel fault-block ranges, these high mountains lie in the rain shadow of ranges to the west. They have a semi-arid climate that creates a long summer climbing season. Many obscure yet spectacular areas are found in these ranges.
"Idaho's Lost River Range, it's probably the most spectacular unknown range in the lower 48. No one in Wisconsin,or pick a state, has heard of them. For that matter, many people in Idaho have not heard of them."
Only separated by narrow river drainages, these ranges provide an almost impenetrable mountain wall from the Snake River Plain to Stanley Basin. Some of the more well known Eleveners are located in these ranges, including Old Hyndman Peak and Castle Peak.
