Mount McAdie, Mountain summit in Sierra Nevada, California, United States
Mount McAdie is a summit in the Sierra Nevada featuring three distinct peaks along the main crest, with the northern peak reaching about 13,805 feet (4,206 meters). The mountain's multiple summits create a complex ridge structure that dominates this section of the range.
The mountain was named in 1905 by James E. Church to honor Alexander G. McAdie, a meteorologist with the U.S. Weather Bureau in San Francisco. This naming reflects the early 1900s practice of dedicating mountain peaks to scientists who studied weather and climate.
The mountain marks the boundary between Sequoia National Park and John Muir Wilderness, showing how different protected areas divide the landscape. Visitors standing here can see how the management and character of the two zones differ from this vantage point.
The standard climbing route accesses the summit through Arc Pass and requires rock scrambling at class 3 difficulty with careful movement between the separate peaks. Expect the terrain to be steep and exposed in sections, so solid footing and balance are essential throughout the approach.
The mountain stands at the junction of Inyo and Tulare counties, creating an unusual administrative boundary line across the high country. From here visitors can spot Mount Whitney, one of the highest peaks in the contiguous United States, which rises nearby and is visible on clear days.
