Climbing the Via the Calamity Brook Trail

From the Upper Works trailhead near Tahawus, New York, or the Adirondak Loj, Marshall is trailless, usually reached via the Herbert Brook herd path from Flowed Lands. The climb follows the brook with mud, rock steps, and slick footing, ending at a wooded summit with limited views. The interior is remote with fast-changing weather. It is often paired with Iroquois or done on its own long loop. Plan a big day of many miles, start before dawn, and carry a map and headlamp.
