Vertebrae ridge is a prominent feature near Chatter Creek. John Dunlop offers this photo of Vertebrae ridge taken while tree skiing on the East Ridge, a popular spot for Chatter Creek cat skiers. Miles to the north (to the left of the picture), a snowcat road crests the ridge at an elevation of almost 10,000 ft., giving Chatter Creek guests access to skiing on Vertebrae Glacier and its "top-of-the-world" vistas. 

Chatter Creek's flagship lodge, the 9300 sq. ft. Vertebrae lodge, is named after this ridge.

Thanks for the picture, John.
