Mount Tom, Mountain summit in Inyo County, California.

Mount Tom is a 13,658-foot peak in the Sierra Nevada, east of the Sierra Crest and within the John Muir Wilderness. With Basin Mountain to the south, it dominates the western skyline of the upper Owens Valley. The Owens Valley floor lies at just over 4,000 feet, giving nearly 10,000 feet of relief.

The Owens Valley Paiute called this peak Winuba before Thomas Clark became the first European to reach it in 1860. Mining activity later brought interest to the area due to mineral deposits found in the rock.

The peak draws mountaineers seeking high-altitude challenges in the Sierra Nevada and serves as a landmark for those exploring the range. The surrounding area reflects its mining heritage through old structures and the activities that once shaped the valley.

The main access is from Horton Creek Canyon on a trail that demands endurance and proper acclimatization for the elevation gain. Summer and autumn offer the best conditions when snow is gone and weather patterns are more stable.

Mount Tom and neighbouring Mount Morgan were part of the Pine Creek mining operation, a major tungsten producer for much of the 20th century. The scheelite ore deposits are now largely depleted and the mines have closed. The peak's Paiute name, Winuba, means "Standing Tall".
