- 1:24,000 (7.5-Minute) Maps
- The Map Library has the current quadrangles in the 1:24,000 topographic map sets for the 19 western states (from North Dakota south to Texas and west). We also have superseded quadrangles for California.
- Search the Geographic Names Information System (GNIS)
- The GNIS is a database of over 2 million physical and cultural geographic features in the United States. Search for a place or feature name and
display the full record to get a list of USGS 7.5-minute quads on which the feature is shown.
