Hike the St. Mary's Glacier trail (3/4 mile) at dusk to watch the FULL MOON rise over Yankee Hill. Hike back down by moonlight (or flashlight). Parking is available in private lots near the trailhead for $5. Meet at the trailhead at 4:45pm for the FREE guided hike. (This event is weather-dependent. If the sky is cloudy, the hike will be cancelled and announced on this Facebook page.)
