About this file
This document is a topographic map of the Dinsmore, California area produced by the U.S. Department of Agriculture Forest Service. The map covers portions of Humboldt and Trinity Counties within the Six Rivers National Forest, with coordinates ranging from approximately 123°30' to 123°37'30" west longitude and 40°22'30" to 40°30' north latitude.
The map displays elevation contours at 160-foot intervals, terrain features including mountains, ridges, canyons, and waterways, and identifies significant landmarks such as Dinsmores-Humboldt County Airport, Southern Trinity High School, gaging stations, and two pipeline corridors. Notable geographic features include Buck Mountain, Swayback Ridge, Mad River Ridge, and various peaks ranging from approximately 2,400 to 5,185 feet in elevation. The document includes benchmark elevations (BM 2401 through BM 2603) and mileage markers (Miles 48-61). The map was compiled from aerial photographs taken in 1984 and revised from 1993 photographs, with partial field verification by the U.S.D.A. Forest Service in 1995. An entrance to Route 1 is marked on the map. The map uses the North American Datum of 1927 and California State Plane Zone 1 projection at a scale of 1:63,360 (one inch to one mile).
