Mountain High opened Saturday November 5, 2011, one of its earliest openings ever. The snow guns have been blazing and natural snow has been falling so Los Angeles' closest terrain park is BACK. New pro team riders Cory Cronk, Harrison Gordon, Kyle Lopiccolo and Spencer Link along with AM team riders Nick Sibayan and Traver Haas connected with friends Erik Leon and Ben Rice for a day of early season shredding.
