The montane ecosystem is a dynamic ecosystem that transforms in the winter. As the snow falls and the temperatures drop, plants and animals must adapt to survive in harsh conditions. Join us for a moderate 1.5-mile hike as we explore this ecosystem. *Transportation from Boulder is available for non-mountain drivers. Details provided upon registration* Registration for most programs begins on the 20th of the month before the event. Registration required. Register .tribe-events-c-subscribe-dropdown{display:none;}
