A detailed map showing the Great Salt Lake, Utah Lake and Sevier Lake, with the Humboldt Mountains at left edge.
Includes the region from the Great Salt Lake and across the flats to the Humboldt range. Several proposed railroad routes noted, including one earlier surveyed in 1854 through the To-a-no Mountains.
Very good depiction of the Emigrant Road skirting north of the lake.
Wheat considers this an excellent map "due in large part to Egloffstein's work as Topographer for the Route."
