Mineral King Area in the Sierra Nevada Mountains of California that the U.S. government opened to private development in the 1960s. Walt Disney put in a bid, which was accepted by the government. However, a groundswell of criticism arose over what environmentalists felt would be the desecration of a major untouched wilderness area.

Congress voted to make the Mineral King area part of Sequoia National Park, and no private development was allowed.
