Alley The Half Pipe at Liberty Mountain has since been removed as it was deemed too much work to maintain and cover with snow. The Half Pipe was usually only open for at most a month of the ski season, but some years not even open at all. The area where the Half Pipe was located was filled in and is now the East Side terrain park. Statistics Elevation: Front base , Back base . Summit: . Vertical Drop: Front side , Back side .
