Saddle Mountain anchors the south end of Idaho's Lemhi Range and is one of the range's most prominent and visible summits from the Snake River Plain. It is considered one of the range's more serious objectives, with long approaches, large elevation gains, and real route-finding difficulty on every line to the summit.
The mountain rises about 6,000 feet above the Little Lost River Valley near Howe, Idaho. Named approaches include the Middle Canyon route and the Cedar Canyon route, both long lines up drainages on the peak's flanks, as well as a west gully/northwest shoulder line. Guidebook and trip-report sources describe all of them as long, with significant elevation gain and route-finding challenges, rather than pointing to one clearly easiest line.
