Hiking Trails and Topographic Maps
USGS 1:24,000-scale topo maps, also known as 7.5-minute quads, can provide valuable information to anyone hiking
in the United States. Each map covers a four-sided area with 7.5 minutes of latitude and 7.5 minutes of longitude. Contour lines on the maps portray the shape and elevation of the land. Campgrounds, trails and water sources are just a few of the many features represented on these maps.
When you're planning a hike, use this site to locate the 7.5-minute quadrangles that cover the area you're interested in exploring. If the older, Digital Raster Graphics (DRG) topo maps are available then download copies—many of these 7.5-minute quads identify trails and other features that may not be included on the newer, PDF topo maps. If there's PDF topo maps available then download these too, and compare their features (e.g., water sources) with the DRG maps. Print copies of the maps and bring them with you on the trail.
