New England Quad Maps Adding Trails Print E-mail
Written by USGS   
Thursday, 30 July 2015

Newly released US Topo maps for New Hampshire, Vermont, Connecticut, Massachusetts and Rhode Island now feature selected trails and other substantial updates

Several of the new US Topo quadrangles for New Hampshire and Vermont now display parts of the Appalachian National Scenic Trail (A.T.) and other selected public trails. Also, parts of the new maps for Connecticut and Massachusetts feature segments of the New England National Scenic Trail as well as sections of the A.T. Further, all of these revised New England maps, to include new US Topo maps for Rhode Island, highlight significant additions to the new quads such as map symbol redesign, enhanced railroad information and new road source data.

“US Topo maps are the ‘gold standard’ for mapped information,” said Fred Dieffenbach, who coordinates environmental monitoring along the A.T. for the National Park Service, “And the inclusion of the Appalachian National Scenic Trail in this latest update illustrates the significance of this prized resource to the American public.”

For East Coast residents, recreationalists and visitors who want to explore the featured New England trails by biking, hiking, horseback or other means, the new trail features on the US Topo maps will be useful.

The Appalachian NST is a public footpath that traverses more than 2,100 miles of the Appalachian mountains and valleys between Katahdin, Maine (northern terminus), and Springer Mountain, Georgia (southern terminus). The Trail winds through scenic, wooded, pastoral, wild, and culturally resonant lands along this ancient mountain range. With more than 99% of the A.T.’s corridor on Federal or State land, it is the longest continuously marked, maintained, and publicly protected trail in the United States.

“The National Park Service has committed significant resources to understanding the environmental health of the lands and resources that characterize the Appalachian Trail along its entire length,” Dieffenbach continued. “It is extremely gratifying to know that its inclusion in the most recent update was a high priority, and clearly validates the efforts of all the people involved with the management of the A.T.”

The New England NST covers 215 miles from Long Island Sound across long ridges to scenic mountain summits in Connecticut and Massachusetts. The trail offers panoramic vistas and close-ups of New England’s natural and cultural landscape: trap rock ridges, historic village centers, farmlands, unfragmented forests, quiet streams, steep river valleys and waterfalls 

The USGS partnered with the National Park Service, the Appalachian Trail Conservancy and other organizations to incorporate the trail data onto the updated New England US Topo maps. These two NST’s join the Ice Age National Scenic Trail, the Pacific Northwest National Scenic Trail the North Country National Scenic Trail, Pacific Crest National Scenic Trail, and the Arizona 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.

Some of the other data for new trails on the maps is provided to the USGS through a nationwide “crowdsourcing” project managed by the International Mountain Biking Association (IMBA).  This unique crowdsourcing venture has increased the availability of trail data available through The National Map mobile and web apps, and the revised US Topo maps.

During the past two years the IMBA, in a partnership with the MTB Project, has been building a detailed national database of trails. This activity allows local IMBA chapters, IMBA members, and the public to provide trail data and descriptions through their website. MTB Project and IMBA then verify the quality of the trail data provided, ensure accuracy and confirm the trail is legal. 

These new maps replace the first edition US Topo maps for these eastern states 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:

§ Appalachian National Scenic Trail

§ Pacific Crest National Scenic Trail

§ Continental Divide National Scenic Trail

§ North Country National Scenic Trail

§ Ice Age National Scenic Trail

§ Potomac Heritage National Scenic Trail

§ Natchez Trace National Scenic Trail

§ Florida National Scenic Trail

§ Arizona National Scenic Trail

§ New England National Scenic Trail

§ Pacific Northwest National Scenic Trail
