About this collection

This project is comprised of General Land Office original public land survey notes 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.
