The pass was named after the nearby Sylvan Lake and was formed by frost action breaking the rocks. The park road through the pass is closed in winter and avalanches are a common seasonal danger. Major reconstruction is planned for the road through the pass between 2004 and 2006.


The original road through the pass was designed by a Captain Hiram Chittenden of the Army Corps of Engineers.
