“The USGS has expanded an excellent working relationship with the U.S. Forest Service to include adding their recreational trails to the data being integrated into The National Map and on our US Topo maps,” said Kari Craun, director of the USGS National Geospatial Technical Operations Center. “The value of adding trails in areas like Bridger-Teton is high because of the number of people using the trails. We are very excited about taking this first step toward incorporating U.S. Forest Service trails information on US Topo maps nationwide.”
The U.S. Forest Service has provided boundary and road data for the US Topo map series for the past five years, and is now working on a national dataset of recreational trails.
Also, a number of the new Wyoming maps contain segments of the Continental Divide National Scenic Trail (CDNST) and other selected public trails. Further substantial upgrades to the new quadrangles include map symbol redesign, enhanced railroad information and new road source data. Some of the data for the trails is provided to the USGS through a nationwide “crowdsourcing” project managed by the International Mountain Biking Association.
The 3,100-mile long CDNST runs from Canada to Mexico through Montana, Idaho, Wyoming, Colorado, and New Mexico. Crossing the spine of the North American continent numerous times, it traverses some of America's most spectacular and isolated scenery, offering views unlike any other trail in the world.
This NST joins the Ice Age National Scenic Trail, the Pacific Northwest National Scenic Trail the North Country National Scenic Trail, the Pacific Crest National Scenic Trail, the Arizona National Scenic Trail, the Appalachian National Scenic Trail, the Natchez Trace National Scenic Trail and the New England National Scenic Trail as being featured on the new US Topo quads. The USGS hopes to eventually include all National Scenic Trails in The National Map products.
Additionally, the new Wyoming US Topo maps will continue the inclusion and improvement of Public Land Survey System data. Wyoming was one of the first states to display this topographic layer several years ago. PLSS is a way of subdividing and describing land in the US. All lands in the public domain are subject to subdivision by this rectangular system of surveys, which is regulated by the U.S. Department of the Interior.
These new maps replace the first edition US Topo maps for Wyoming and are available for free download from The National Map, the USGS Map Locator & Downloader website , or several other USGS applications.
To compare change over time, scans of legacy USGS topo maps, some dating back to the late 1800s, can be downloaded from the USGS Historical Topographic Map Collection

|The National Trails System was established by Act of Congress in 1968. The Act grants the Secretary of Interior and the Secretary of Agriculture authority over the National Trails System. The Act defines four types of trails. Two of these types, the National Historic Trails and National Scenic Trails, can only be designated by Act of Congress. National scenic trails are extended trails located as to provide for maximum outdoor recreation potential and for the conservation and enjoyment of nationally significant scenic, historic, natural, and cultural qualities of the area through which such trails may pass.
There are 11 National Scenic Trails:
