In the 1960s Disney proposed to construct a ski resort in Mineral King, which would have brought one of the most intense developments in the history of the upper Kaweah watershed. The resort would have included 22 ski lifts, a 1,030-room hotel, ten restaurants, and a railroad along the canyon of the East Fork Kaweah River to transport visitors from a parking area further down the mountain. Environmentalists fought against the proposal for many years, and in 1978 the National Parks and Recreation Act designated the area as part of Sequoia National Park.
