Laws & Policies
Establishment of a National Trails System
The National Trails System Act of 1968 authorized a feasibility study for a "Potomac Heritage Trail," subsequently completed and published by the Bureau of Outdoor Recreation in 1974. In 1983 an amendment to the Act (P.L. 98-11) recognized a corridor for development of the Potomac Heritage National Scenic Trail based on the narrative and a generalized map in the feasibility study. Such "authorizing" legislation for the Trail states that, initially, the Trail will be "within the external boundaries of federal facilities." The Act also authorizes the Secretary of the Interior to enter into agreements with various entities for management of Trail segments. The Departmental Manual delegates responsibility for administration to the National Park Service.
Creating Continuity of Experience throughout the Trail Network
The Trail embodies a wide range of resource types, management interests and users. The need to establish and maintain physical, graphic and interpretive continuity between and among Trail segments is essential to experience the Trail as a network with national significance.
Identity Guidelines for Trail Partners:Trail segment managers are encouraged to review and use a set of guidelines to develop graphic and interpretive continuity among Trail segments. Please click here to download a set of the guidelines (1.2 MB). Assistance is available from the Trail Office.
Trail Route Marking: Use of the official Trail marker (i.e., logo) is the most common element to establish continuity throughout the Trail network and to provide users with a measure of confidence that they have located and/or are following an intended route. Trail managers are encouraged to use the Trail marker at trailheads and at major transitions between trail types and trail corridor attributes. In places where blazes are used to mark routes, Trail segment managers are encouraged to use a color that complements the Trail logo-- white; a dark blue (Pantone Color Management System 299); or black--to establish and maintain a graphic identity and to ensure adequate contract between route markers and background colors.

Did You Know?
The round holes you see in the rocks along the River Trail in Great Falls National Park were carved by the Potomac. Some of these potholes are large enough to stand in and can take over 500 years to form.
