1971 Map of Silver Island Pass

About this map

Silver Mountains dominate the southeastern horizon of this 1970s survey, marking a sharp vertical contrast to the expansive white flats of the Great Salt Lake Desert. The terrain is characterized by the extreme desolation of the Alkali or Mud flats, where sparse water sources like Springs and an isolated Spring appear along the base of the mountain range. This desert landscape is further defined by shifting Sand Dunes that creep across the basin floor. Human presence is minimal, recorded only by a solitary Jeep Trail that skirts the northwestern dunes, hinting at the difficult passage through this arid corridor. The map captures the rugged crossing at Silver Island Pass, a critical point of relief for those navigating the boundary between Tooele and Box Elder counties in the early 1970s.
