This bill proposes to amend the National Trails System Act to initiate a feasibility study for the potential designation of the Bonneville Shoreline Trail . The legislation specifically directs the Secretary of the Interior to conduct this study. The Bonneville Shoreline Trail is described as a system of existing and potential trails spanning approximately 280 miles. It runs from the Idaho-Utah border south to Nephi, Utah, following the geological feature known as the Bonneville bench, which was formed by the ancient Lake Bonneville.
