Winter Ramblings

with Eileen Kreutz

Calendar Oct 23, 2025

Each session will be a walk or snowshoe in various meadows, woodlands, or mountains in the vicinity of Farmington. The travel time to the trailhead will generally be between 30 and 45 minutes, and participants should plan to be on the trail for 1 to 2 hours. Efforts will be made to avoid difficult terrain, and a makeup date will be scheduled in the event of cancellation.

Approximately one week before each session, participants will receive an email detailing the travel plan, providing information about the destination, and offering suggestions on what to bring.

October 23 or 24, 2025, at 10:00 am, weather dependent, will be led by Barb Toner with forester Jon Dody. Jon will take us on a walk through the woods, sharing what he looks for from a forest management perspective, taking into account the landowners' objectives.
