A quick and easy way to download and print any USGS 7.5 minute topographic quad
 

National Geographic is allowing everyone to easily download any USGS 7.5 minute topo map in the continental U.S. as a multi-page PDF that can be printed on letter size paper on any printer. These are the same topographic maps that were published by the U.S. Geological Survey for decades, with nice additional features from our much-loved, but discontinued TOPO! software product, including:

Page 1 is an index map showing each of the printable quarter-quad maps in their broader context
Pages 2-5 are the topo quarter-quads, sized and scaled to print on US-letter size paper
We've added hillshading to help visualize the topography
NOTE: Since the USGS stopped updating their printed topos decades ago, some of these maps do not accurately reflect the current landscape. For the most detailed and up-to-date maps of popular outdoor recreation areas, we recommend our Trails Illustrated maps.
