2020 Map of Floating Island

About this map

Silver Island Mountains dominate the western half of this Tooele County landscape, rising sharply from the surrounding flats. The survey captures the topographic transition from the high point at Cobb Peak down through Silver Island Canyon into the expansive Great Salt Lake Desert. This arid basin floor is traversed by several functional tracks, including Floating Island Rd and Silver Island Canyon Rd, which connect the isolated peaks to the broader salt flats. In the eastern portion of the quadrangle, the namesake Floating Island stands as a distinct topographical outcrop, appearing as a lone island of relief within the desert expanse. Historically, the map documents the geographic context of the region, including the proximity of Donner Canyon Rd, reflecting the difficult terrain faced by early travelers crossing these salt basins.
