Not only has National Geographic made it easy to find the United States Geological Survey quadrangle you’re looking for due to their IS map that you zoom into, but they’ve also made it free and easy to print from home.
After you conduct your search and find the desired quadrangle, NatGeo gives you a five-page pdf consisting of the overall map along with the map broken up into quarters, one per page allowing you to print it on a standard sized printer and tape or glue inverting together.
As a bonus, NatGeo has also added hill shading to the maps.
