At only 1040', Windbeam is the fifth lowest mountain on our NJ1K list, but Windbeam actually takes more vertical climbing to summit than nearly any other mountain in New Jersey.
From the south and west Windbeam is a 700' climb. The Highlands trail's ascent up Windbeam from the south is one of the longest sustained steeps in New Jersey; even providing a false summit and views at Little Windbeam. Even the easier and more frequently climbed western climb via the Stonetown Circular is a 600' climb. Even from the col with Bear Mountain Windbeam is over a 500' climb.
Windbeam and several other fine mountains in the Wyanockies are traversed by the Stonetown Circular. In this picture, Mighty Windbeam as seen from Signal Rock.
