KLAMATH BASIN GENERAL LAND OFFICE (G.L.O.) SURVEY NOTES TRANSCRIPTION

The General Land Office original public land survey notes have been manually transcribed onto the respective U.S.Geological Survey topographic 7.5’ quadrangle maps. These notes contain valuable information regarding site conditions at the time of the survey (mid-1800’s – early 1900’s), including vegetative cover, location of streams and other hydrologic features, and soil conditions. Although public information, these data have been largely inaccessible to the general public due to legibility and lack of readily visualized spatial referencing. This project covers the transcription of GLO notes for 85 quadrangles in the Upper Klamath Basin. Use of these data include support and documentation for ecosystem restoration efforts by public and private entities, as well as providing valuable historical records of the original survey parties.
