Bureau of Land Management

These maps, hand-drawn by surveyors hired by the United States General Land Office, were originally made to document the land claims made by settlers to this region. Though they can vary in detail, they are a rich cartographic resource showing the location of homesteads, roads, buildings and landforms. The majority of the maps date from 1852-1910.

The easiest way to access the maps is to use the map viewer provided by the BLM

  1. Click on a grid square on the map for the location you are interested in
  2. Select a map from the section “Survey Plats” (the date is in the third column)
  3. Click "View" to open a high-resolution scan of the map
