National Conservation Area is a designation for certain protected areas in the United States. They are nature conservation areas managed by the Bureau of Land Management (BLM) under the National Landscape Conservation System.
Restrictions vary between these conservation areas, but generally they are not leased or sold under mining laws and motorized vehicle use is restricted, unlike many other BLM areas.
The Alaska National Interest Lands Conservation Act (ANILCA) is a United States federal law signed by President Jimmy Carter on December 2, 1980. ANILCA provided varying degrees of special protection to over 157 million acres (640,000 km) of land, including national parks, national wildlife refuges, national monuments, wild and scenic rivers, recreational areas, national forests, and conservation areas. It was, and remains to date, the single largest expansion of protected lands in history and more than doubled the size of the National Park System.
The Act provided for 43.585 million acres (176,380 km) of new national parklands in Alaska; the addition of 9.8 million acres (40,000 km) to the National Wildlife Refuge System; twenty-five wild and scenic rivers, with twelve more to be studied for that designation; establishment of Misty Fjords and Admiralty Island National Monuments in Southeast Alaska; establishment of Steese National Conservation Area and White Mountains National Recreation Area to be managed by the Bureau of Land Management; the addition of 9.1 million acres (37,000 km) to the Wilderness Preservation System, and the addition of 3.35 million acres (13,600 km) to Tongass and Chugach National Forests.
The Red Rock Canyon National Conservation Area in Clark County, Nevada, United States, is an area managed by the Bureau of Land Management as part of its National Landscape Conservation System, and protected as a National Conservation Area. It is about 15 miles (24 km) west of Las Vegas. More than three million people visit the area each year.
The conservation area showcases a set of large red rock formations: a set of sandstone peaks and walls that were formed by thrust faults including the Keystone Thrust. The walls are up to 3,000 feet (910 m) high, making them a popular hiking and rock climbing destination. The highest point is La Madre Mountain, at 8,154 feet (2,485 m).
