The National Atlas of the United States of America is a collaborative work established in 1997 by the U.S. Geological Survey and its Atlas Partners. The National Atlas is designed to provide easy to use, map-like views of our natural and socio-cultural landscapes for a better understanding of the complex relationships between environments, places, and people.
The National Atlas maintains a database of a number of coverages that might be useful. The National Atlas files have a scale of 1 to 2 million, so they are less accurate then the 1:24,000 scale data available on the Digital Line Graph page. However two files are useful for a general overview of the area around Crater Lake National Park: Federal Lands and Counties. These two files are available for download below.Image of the flying eagle over the North America map is acquired from http://www-atlas.usgs.gov/.
