Twentynine Palms, also called 29 Palms, is a city in San Bernardino County, California, serving as a gateway to Joshua Tree National Park and the Mojave Desert. The area was first explored by Colonel Henry Washington, who found the Chemehuevi people living near a spring called “Mar-rah” or “Oasis of Mara.” The city was named after the 29 palms planted by the Serrano tribe around this oasis. A post office opened in 1927, and Utah Trail commemorates 19th-century pioneers traveling from Utah to Twentynine Palms.
The city is located near Joshua Tree National Park, designated a national monument in 1936 and a national park in 1994. Twentynine Palms also hosts the Marine Corps Air Ground Combat Center, established in 1952, and a small reservation for the Twenty-Nine Palms Band of Mission Indians.
