Extremely detailed map with very fine hachure to indicate mountainous elevations. The map extends from Brown's Hole east of today's Vernal to the Great Salt Lake and south to below Fillmore. Locates the Emigrant Road to California. Several Proposed Railroad lines are shown. One crosses the Green River near Black's Fork, continues past Fort Bridger (Wyoming) and along the Weber River to Ogden City where it turns south. Another railroad leaves the Wasatch Mountains via Timpanogas Canyon, and another heads west from the Oquirrh Mountains. Wheat considers this an excellent map "due in large part to Egloffstein's work as Topographer for the Route."
