1991 Map of Crater Island SW

About this map

The Donner-Reed Trail cuts across the southeastern portion of this map, tracing a historic path of westward expansion across the unforgiving Great Salt Lake Desert. The terrain is characterized by the stark transition from the steep eastern slopes of the Pilot Range to the expansive, level Mud flats. This landscape is defined by its scarce water sources, where vital points like Donner Spring, South Patterson Spring, and various unnamed Springs emerge along the mountain front. To the south, Sand Dunes shift near the boundary of Box Elder Co and Tooele Co. The mapping illustrates the environmental challenges faced by early travelers, showing the exact relationship between the seasonal flows of Bettridge Creek and the hazardous mudflats that lay between these springs and the next reliable mountain crossing.
