Zzyzx

Zzyzx, formerly Soda Springs, is an unincorporated community in San Bernardino County, California, within the boundaries of the Mojave National Preserve, managed by the National Park Service, an agency of the U.S. Department of Interior, as public land. It is the former site of the Zzyzx Mineral Springs and Health Spa and now the site of the Desert Studies Center. The site is also the location of Lake Tuendae, originally part of the spa, and now a refuge habitat of the endangered Mohave tui chub.

Zzyzx Road is a 4.5-mile-long, part paved and part dirt, rural collector road in the Mojave Desert. It runs from Interstate 15 generally south to the Zzyzx settlement.
