Happy anniversary to the Wilderness Act! On September 3, 1964, President Lyndon Johnson signed this landmark conservation legislation. The BLM has stewardship responsibilities for 223 Wilderness Areas with over 8.7 million acres in 10 Western States. These areas are protected in their undeveloped state and offer outstanding recreation opportunities for visitors willing to experience nature on its own terms. BLM managed wilderness areas include vast southwestern deserts, red-rock canyons, rugged Pacific coastline and alpine peaks.
