Kathleen at Cold Brook Fall. Kathleen, where did you get that nasty scrape? We finally finished the hike back to Appalachia on US 2 at: 10.9 1306 6:45 PM. The 11-mile hike was completed successfully and happily in 11:15 including 4,790 feet of elevation gain by all the participants and was raved as one of the most challenging, exhausting and satisfying hikes ever!
