Salduro, Utah Salduro, Utah Salduro (also Salduro Siding) is a ghost town located in Tooele County, Utah, United States. The name "Salduro" is a combination of Spanish words and means hard salt. The settlement was located on the geologically-significant Salduro Salt Marsh, also known as the Bonneville Salt Flats. Bonneville Speedway is located approximately north of Salduro. Salduro formed next to the Western Pacific Railroad, which was completed in the early 1900s. Significant salt beds were identified during the construction of the railroad, and several mining claims soon followed. After several years of unprofitable attempts to produce salt, the claims were leased
Bonneville Salt Flats ShootOut in September. The Southern California Timing Association and the Utah Salt Flats Racing Association organizes and plans the multi-vehicle events, but all event promoters contribute to prepping and maintaining the salt. "Speed Week" events in August were canceled for the second year in a row in 2015, due to poor conditions of the salt in certain parts of the flats. The salt flats had been swamped by heavy rains earlier in the year, which usually happens, but the rains also triggered mudslides from surrounding mountains and onto a section of the flats used for the land-speed racing courses.
