Visual reminders of the glacial past are all around you in the rocky landscape of the park. Grooves and scratches in the rock (generally in a north-south direction) indicate how the glaciers moved. As these massive fields of ice pushed across the land, loose gravel and rocks were scooped up and carried along, gouging grooves into the bedrock of the Precambrian Shield.
The forest is dominated by jack pines of a uniform height, due to a forest fire in 1910 which opened all the pinecones at once. Balsam, spruce, aspen, alder, and maple have intermingled with the pines. This dense forest canopy shades a community of other plant life, including many edibles such as blueberries, cherries, hazelnuts, raspberries, and strawberries.

Black bear, moose, and deer are occasionally seen, as are red fox, weasel, mink, and otter, especially in early spring and late fall. The bird community includes more than 60 species, among them the great blue herons, loons, night hawks, belted kingfishers, Canada jays, and various waterfowl.
