Winter in the Arboretum
14 January 2011If you have not had a chance to appreciate the quiet solitude of the prairies, forests, and oak savanna in Carleton’s Cowling Arboretum, we encourage you to get out, especially on cross country skis or snowshoes. Both are available to check out from the Recreation Center. Snowshoes are a great way to get off the trails and explore some of the more remote parts of the Arboretum. If walking is your preferred method of winter travel in the Arboretum, we have some tips for you as well.
