Peak Geography & History

Rising 6,288 feet in the heart of the Presidential Range, Mount Washington sits at the meeting point of three major storm tracks: the Atlantic Seaboard, the Gulf of Mexico, and the Pacific Northwest. As a result, this mountain experiences some of the most ferocious and rapidly fluctuating weather on the planet. The Tuckerman Ravine Trail ascends steep boulder headwalls out of Pinkham Notch into the alpine zone, where krummholz gives way to fragile arctic-alpine tundra and severe wind chill.

Required Gear Checklist
