About Big Maria Mountains Wilderness
The Big Maria Mountains Wilderness encompasses 45,384 acres and is managed by the BLM's Palm Springs-South Coast Field Office . In 1994 the Big Maria Mountains Wilderness became part of the now over 109 million acre National Wilderness Preservation System. In wilderness, you can enjoy challenging recreational activities and extraordinary opportunities for solitude. The terrain of the Big Maria Mountains varies from gently sloping bajadas to numerous rough, craggy peaks disjointed by steep canyons. The northern boundary lies south of a major drainage known as Big Wash, and the eastern edge parallels State Highway 95 and the Colorado River. The west and south boundaries follow power lines and contours along the base of the mountains. Foxtail cactus and California barrel cactus dot the landsc
