This region of shadowy slot canyons, mind-bending geological formations and expansive views of Lake Mead is jointly administered by the National Park Service and the Bureau of Land Management. Solitude and silence are common throughout the 3,521 acres of narrow canyons and gravelly washes found inside Lake Mead NRA. The landscape here displays a thriving Mojave Desert habitat of creosote bush, black brush, yucca, Joshua tree and desert willow. Watch for bighorn sheep, the banded Gila monster and the desert tortoise.
