1991 Map of Crater Island

USGS Topo · Published 1992

About this map

Donner-Reed Trail cuts across the southern portion of this landscape, marking the historic path taken by the ill-fated pioneer party. The route traverses the lower edge of the Crater Island Mountains at Donner-Reed Pass, providing a window into the difficult conditions of early westward migration. This terrain is defined by the stark transition between the elevated peaks of Silver Island and the surrounding expanse of Mud, an environment where water sources like Flowing Well and Drill Hole were essential for survival. Industrial activity is indicated by several Prospects and a Mine located on the northern slopes of the island. The map also identifies local geological features such as Caves, which dot the rocky outcrops and serve as points of interest for historical and geological research along the border of Box Elder Co and Toole Co.
