- Official USGS Description: Swift Run Gap, 31.5 mi NE. of, along Skyline Drive; 3.8 mi SW. of Thornton Gap; at Pinnacles Overlook; 89 ft SE. of junction of Skyline Drive at NW. turnout to overlook; 87 ft W. of junction of Skyline Drive at E. turnout to overlook; 28 ft S. of Skyline Drive; in small island formed by drive and turnout rd.; in rock outcrop; standard tablet stamped “120 MLS 1963 3326”
This disk can be found in the same boulder that once held THORO ERDL AZ MK 1 (described in HW3272). All that remains of that mark is a drill hole, but 120 MLS was our bonus when we went to the Pinnacles Overlook to search for the azimuth mark.
