Historical and current Topographic Maps (scale 1:24000) including the area of the Santa Rita Experimental Range (SRER) can be downloaded from the TopoView page of the U.S. Department of the Interior Geological Survey (USGS) by searching or selecting the area of interest on the TopoView Map. Since 1884, the purpose of these maps has been to display the geography of the United States, including information such as place names, hydrography, and contour lines (USGS National Geospatial Program)
More particularly, the SRER is included in the following maps: 

  • Corona De Tucson
  • Esperanza Mill
  • Green Valley
  • Helvetia
  • Mount Wrightson
  • Sahuarita

All topographic maps are available in different formats (*GeoPDF, *GeoTiff, *.JPEG, *.KMZ) for download.
