Triple Divide Peak is a mountain on the boundary between Yosemite National Park and the Ansel Adams Wilderness in Madera County, California. It is located north of Walton Lake and southeast of Merced Peak. Its name refers to the fact that it lies on the boundaries of three distinct watersheds, namely those of the Merced, South Fork Merced, and San Joaquin rivers. Climate According to the Köppen climate classification system, Triple Divide Peak is located in an alpine climate zone. Most weather fronts originate in the Pacific Ocean and travel east toward the Sierra Nevada mountains. As fronts approach, they are forced upward by the peaks (orographic lift), causing moisture in the form of rain or snowfall to drop onto the range.
