This map is from Campbell's report that eventually persuaded congress to fund two Pacific Wagon Roads; a southern route and a central route. The map extends to show the route they took between the City of Rocks, past Thousand Spring Valley, Humboldt's Canyon, Fremont Canyon, Stony Point Meadows to Tutts Meadows where the Humboldt River is joined. From there the map details the region around Pyramid and Honey Lakes and south to Washoe Lake and Lake Bigler, ending at Carey's Mill at Johnson's Pass. The Proposed Road is clearly shown.
