Join Master Naturalist, Mike Quilan, to celebrate the change of seasons a little early. We’ll look for signs of winter and close out the shortest day of the year as we watch the sunset from the Observation Deck. If we are lucky we may catch a glimpse of the night’s full moon – the Long Night Moon. This moon is in view longer than any other full Moon of the year. All ages. Free with $6 per vehicle park admission. Current health guidelines and registration required.
