Eastern States Topographic Maps

This group of map cases house the U.S. Geological Survey 7.5 and 15-minute topographic quadrangles covering eastern U.S. states from the Rocky Mountains to the Atlantic coastline. The collection is historic dating back to the late 1890's. The set also includes quadrangles published by the Corps of Engineers, the Army Map Service, and the Defense Mapping Agency. For selected states historical editions, are retained on microfilm only.

Sheets are arranged by quadrangle name and then by date. To located the sheet you need, the first step is to consult the USGS state index map and determine the quadrangle name for your area of interest.
