Postal service at La Sal was established on September 12, 1878, when La Sal became an outpost on the mail route from Salina, Utah, to Ouray, Colorado, a 350 mile route through Green River, Moab, and La Sal in Utah and Paradox, Naturita, Placerville, and Ouray in Colorado that was considered one of the strangest and most dangerous in United States Post Office history and for several years the only mail-way. Mail schedules depended on snow depth, river levels on the Price, Green, Colorado, Dolores, and San Miguel, and the hostility of Indians at the time, so delivery could take a month or even six weeks. William Hamilton was the first postmaster, followed by R.R. Simpson in February 1879 and Mrs. Elizabeth L. Ray in August 1879; Ray also helped begin La Sal's first school by using some post office black ink to make a serviceable blackboard. In February and March 1885, snow drifted to ten feet and travel was by snowshoe; the mail carrier from Paradox, Mr. Calan, arrived exhausted after his snowshoes disintegrated, and Jack Silvey relieved him so the mail could go through. William N. Prewer became postmaster on May 28, 1897, soon followed by his brother Fred, a partner in the PCC Cattle Company who planted many fruit trees and poplars that still stand. Between 1878 and 1901 the post office was at Pine Lodge seven miles northeast of here, but in 1901 this site, originally known as Coyote, became the post office and the townsite gradually became known as La Sal, with John Conningham as postmaster and the office in the Ranch House, where one old timer recalled mail being dumped on the dining table for people to sort themselves. In May 1915 Charles Redd became postmaster and the office moved to a small store building east of the Ranch House. About 1916 a new road was built, and a buckboard or white top rig replaced the pony express mail carrier; these rigs also carried passengers and nooned at La Sal. Redd served 43 years, during which the automobile replaced the white top rig. In March 1958 Frances R. White became postmaster, and during the uranium boom the office was designated Third Class. After fire destroyed the post office and store in December 1961, White rented a room in the elementary school and resumed service the following week. A new building owned by Redd Ranches and rented by the Post Office Department was completed and occupied by September 1962, and Roberta J. Wilcox assumed charge in January 1968 as acting postmaster.
