The Ansel Adams Wilderness is a wilderness area in the Sierra Nevada of California, USA. The wilderness is part of the Sierra (majority of the wilderness) and Inyo National Forests. The wilderness spans 231,533 acres (93,698 ha). Yosemite National Park lies to the north and northwest, while the John Muir Wilderness lies to the south.
The wilderness was established as part of the original Wilderness Act in 1964 as the Minarets Wilderness. The 109,500-acre (44,300 ha) Minarets Wilderness was created by enlarging and renaming the Mount Dana-Minarets Primitive Area.In 1984, after his death, the area was expanded and renamed in honor of Ansel Adams, well-known environmentalist and nature photographer who is famous for his black and white landscape photographs of the Sierra Nevada.
Adventurer Steve Fossett died in 2007 after his airplane crashed in the wilderness near Minaret Lake; despite a massive search effort, the wreckage wasn't discovered for over a year.
