HikerNerd rates the Mount Moriah via Stony Brook Hard on a six-tier scale from Easy to Most demanding. The rating comes from the route itself: its 9.6 miles, 3,134 ft of gain, and the steepest quarter mile of trail, with routes known for scrambles or ledges rated a step harder. It is the same scale our NH 4,000-footer difficulty ranking uses.
