The Mt St Louis-Moonstone snow report for Dec 21 is a 16" base depth with 10 of 12 lifts open. Please note ski conditions and snowfall at Mt St Louis-Moonstone are sourced directly from the ski resort and are only recorded during the official ski season's opening to closing dates.
Nearly all trails were open- an impressive achievement in this climate! Well groomed, super fast chairlifts - including the 8 person lift with heated seats, and relatively good snow with some icy spots. Only downside were the crowds but would expect nothing less given the options in Ontario.
Mount St. Louis Moonstone has added snowboard parks, a pipe Monster Groomer, a Magic Carpet, and four snow cams in recent years. The resort has been concentrating on improving its snowboarding conditions as well.
