Join volunteer naturalists on a mostly flat, 3-mile, out-and-back snowshoe walk to an aspen grove at Caribou Ranch. With the leaves gone, we can enjoy the subtle colors of winter and the stories in the aspen bark. While resting among the aspen, we will practice mindful observation. We’ll take time to reflect together on what we’ve observed, what we know about aspen and what remains unknown, and what we can still learn from nature. Registration for most programs begins on the 20th of the month before the event. Registration required. Register Registration is required through Discover Boulder County, Parks & Open Space’s volunteer and event registration system. If you’re new to the system, you'll need to create an account. But it’s easy and we only use your contact information to communicate about events you register for. We will never sell or give your information to a third party.
