The Lemhi Range is a long (approx. 120 mile) Basin and Range chain of mountains, somewhat out of place in east central Idaho. It is more like a major mountain range of Nevada. The Lemhi rise abruptly out of the basalt of the Snake River Plain and run north by NW to terminate just south of the town of Salmon, Idaho.

Much of the range is roadless. The southern roadless area, often called "Diamond Peak" because of that prominent mountain, is separated from the larger "North Lemhi roadless area" by an old area of mining tunnels, roads, and small pits in the middle portion of the range.

The southern part of the range is high, but narrow, with a number of peaks over 11,000 feet in elevation. Aside from Diamond Peak, the most prominent peak is Bell Mountain (11,618 ft.). The southern part of the range is composed mainly of sedimentary rocks -- limestone and dolomite. Metamorphic and scenic Challis volcanics dominate in the broader, but someone lower northern Lemhis.

The North Lemhis have much more water than the Diamond Peak portion, quite a few cirque lakes, and a considerable number of elk, deer, antelope, bear and cougar. Occasionally a few of the offspring of the wolves reintroduced into Idaho show up in the Lemhis. It was also a place where lone wolves were reported from time-to-time prior to the reintroduction of wolves, and recently there is growing evidence of wolf pack activity.

The North Lemhi roadless area is over 250,000 acres in size. If a few regenerating clearcuts and logging roads fading back to nature were closed, the backcountry (semi-wilderness) might reach 350,000 acres.

Long Mountain is over 10,500 feet high, one of many similar peaks on the crest of the northern part of the Lemhi Range.
