Mount Tom is a large and prominent peak near the city of Bishop in Inyo County of eastern California. It is in the Sierra Nevada and east of the Sierra Crest. The mountain is also in the John Muir Wilderness.
The mountain is named for Thomas Clark, a resident of the pioneer town of Owensville, who is credited with being the first to ascend the peak in the 1860s. Mount Tom and Mount Morgan were part of the Pine Creek mining operation which was important producer of tungsten for much of the 20th century although the scheelite ore deposits are now largely depleted and mines have closed.

The Owens Valley, at the base of Mt. Tom, is a little over 4,000 feet, and the summit of Mt. Tom is 13,658, for almost 10,000 feet of relief. The common routes up Mount Tom are not technically difficult, most are class 2-3, but they are all strenuous and long.  Summiting Mount Tom is possible in a single day, but should only be attempted by those in very good physical condition.
Horton Creek Canyon is a common out and back hiking route and 14 mile out and back trail with 5,652 feet of elevation gain.  The trailhead at Horton Creek Canyon is 8000 feet in elevation, it is 3.6 miles hike with about 2000 feet of elevation gain to reach Horton Lake. There campers may, with an overnight wilderness permit, choose to spend the night.
