These maps are available for purchase at the U.S. Geological Survey Store, many Forest & Grassland Offices in the region and other retail outlets. Many Forest Visitor Maps are also available for purchase as georeferenced PDFs on Avenza, for use on mobile devices.

• Forest Visitor Maps for each national forest and grassland provide forest-wide information on attractions, facilities, services, and opportunities.
• National Forest Atlases are full color atlases, containing 8.5-inch by 11-inch topographic quadrangle maps at 1 inch to the mile scale and are available for many of the forests in California.
• Wilderness Maps are topographic maps that show natural features such as mountains, valleys, plains, lakes, rivers, and vegetation using contour lines depicting elevation gain or loss. Each map covers all or part of one wilderness area and the scale is generally 1 inch per mile (1:63,360).

In general, forest visitor and other kinds of maps can be purchased at most Modoc National Forest Offices.
