The Forest Visitor Maps and topographic maps listed below are very useful for showing trails, roads, streams, lakes, recreation sites, major points of interest, and more. They are not updated every year, however, and are notthe legal source of information on which roads and trails are open or what types of vehicles they are open to. For this information, the yearly Motor Vehicle Use Maps (MVUMs) are the legal record of what motorized recreational opportunties are available on Forest Service lands.
US Geological Survey: The national source to find, order, or download topographic maps, including quadrangles or “quads.” The most popular USGS maps are known as "7.5-minute" maps. These maps have a 1:24,000 scale allowing for great detail.
Trails Illustrated:These maps are based on USGS information, modified and regularly revised by National Geographic Maps in cooperation with the USDA Forest Service and local agencies. Trails Illustrated maps are available for every state in the Rocky Mountain Region, with the exception of Kansas. Trails Illustrated maps are available online from the USGS Map Store and the Trails Illustrated Web site.
