When traveling on Cougar Creek Trail you pass through a thick grove of large aspen trees. Although they look like individual trees, they are actually one large organism; the trees are all connected via an underground root system. Aspens groves are actually some of the largest single organisms on earth! In the fall their leaves turn from a bright green to deep shades of yellow and orange. This aspen grove is a wonderful, shaded place rest, take photographs, and enjoy these amazing trees on your hike.
