Zzyzx, California //, formerly Camp Soda and Soda Springs, is a settlement in San Bernardino County, California. 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.
The settlement is in area codes 442 and 760 and ZIP code 92309. The nearest town is Baker, California, 7 miles (11 km) north on I-15. Las Vegas, Nevada is the nearest major city, about 100 miles (160 km) northeast.
Soda Springs, a natural spring, has long seen human activity. The area was a prehistoric quarry site, and projectile points and rock art can be found in the area. The Mojave Road ran past the spring, as did the Tonopah and Tidewater Railroad. Remnants of a wagon road stop and railroad artifacts are readily seen. Evaporative salt mining and mill sites can be found here as well.
The made-up name Zzyzx was given to the area in 1944 by Curtis Howe Springer, claiming it to be the last word in the English language. He established the Zzyzx Mineral Springs and Health Spa in 1944 at the spot, which was federal land, after filing mining claims for 12,000 acres (49 km2) surrounding the springs. He used the springs to bottle his water and provide drinks for travelers through the hot desert. Springer also imported animals from around the country to attract more families to visit his ranch. He used Zzyzx until 1974, when he was arrested by the United States Marshals for misuse of the land as well as alleged violations of food and drug laws, and the land was reclaimed by the government.
Word Ways magazine verified the source of the lexicography as an undated San Bernardino County map published by the Automobile Club of Southern California. The magazine characterized Zzyzx Springs as "a hydrologic feature and a privately owned spa catering to the senior citizen, about 8.5 mi (13.7 km) south of Baker on the western edge of Soda Dry Lake, off the abandoned right-of-way of the old Tonopah and Tidewater Railroad."
Zzyzx was approved as a place name by the United States Board on Geographic Names on June 14, 1984. As is the case with the road, Zzyzx, California, is the USBGN's lexicographically greatest (alphabetically last, at least in English alphabetical order) place name.
