19th century oasis around a lone cottonwood tree and a good spring. Wagon ruts from heavy traffic attracted here are still visible on hill to the southwest. In 1849, Capt. Randolph B. Marcy, U.S. Army camped with his soldiers at this spring as they mapped a gold-seekers' road to California. Capt. Marcy was to return as escort (1851) for Col. W. F. Belknap, en route to establish Fort Belknap (15 miles southwest), and with Maj. Robert S. Neighbors (1854), exploring for Indian reservation sites. Maj. Enoch Steen of the 2nd U.S. Dragoons was here in 1855, platting a route to Fort Riley, Kan. The Leach wagon train camped here in 1857 while opening the Butterfield Overland Mail route, along the Preston Road to Red River. Riding to the north of Red River to fight wild Comanche raiders, two expeditions camped here in 1858: Capt. John S. ("Rip") Ford with Rangers, in April; Maj. Earl Van Dorn with U.S. Cavalry in the fall. Maj. Neighbors in August 1859, escorting Texas Indians to reservations in present Oklahoma, found the spring dry. Water returned, however. Cattlemen used the spring for generations, until in mid-20th century, the water table dropped permanently and the cottonwood died. (1974)
