Hollow Hills Wilderness is a 22,366-acre protected desert landscape near Baker in California’s Mojave Desert, created in 1994 under the California Desert Protection Act and managed by the Bureau of Land Management’s Barstow Field Office. It occupies a broad bajada descending toward the dry lakebed of Silver Lake, with hills on the eastern side rising toward the Turquoise Mountains. Its desert environment includes creosote bush scrub, desert holly, scale scrub, and seasonal wildflowers, while providing habitat for wildlife such as the desert tortoise, the Mohave fringe-toed lizard, and birds including the vermilion flycatcher.
