The bulk of the western slope of the notch is formed by Mount Washington, the highest peak in the northeast United States, reaching above sea level. Mount Washington rises more than above the floor of the notch. A number of glacial cirques are found on this side of the notch. The Great Gulf and its tributary cirques form the largest cirque in the White Mountains. South of the Great Gulf is Huntington Ravine, with a rocky, precipitous headwall renowned for its rock and ice climbing. The slope then dips into the Ravine of Raymond Cataract, a non-glacial V-shaped valley with a notable waterfall. After this comes Tuckerman Ravine, with a uniform, smoother headwall that is known for its high-quality skiing. After passing the Gulf of Slides, a smaller and lesser-known cirque, the notch opens up and continues until Jackson.
