Tuckerman Ravine is a glacial cirque sloping eastward on the southeast face of Mt. Washington, in the White Mountains of New Hampshire. Although it draws hikers throughout the year, and skiers throughout the winter, it is best known for the many "spring skiers" who ascend it on foot and ski down the steep slope from early April into July. In this period, the temperatures are relatively mild but the natural snowpack — which averages up to 55 feet (17 m) in a typical winter — is still adequate to ski most seasons.
