Agassiz Rock Professional Review and Guide

"Louis Agassiz (1807–1873), professor of natural history at Harvard University, used Agassiz Rock to support his theory, which was controversial at the time, of glacial movement. This reservation provides an excellent example of how the great ice sheets of the ice ages shaped the terrain by grinding down mountains, carving valleys, and leaving huge boulders, like the two found by Agassiz, in their wake.

Today you can view these boulders, known as glacial erratics (because of the haphazard way in which they were deposited), by taking a short forty-minute walk around the property. Highlights: Unusual glacial boulder, woodland loop trail."

"This short, rugged hike tours a hillside made spectacular by the handiwork of the Wisconsin Glacier. Two granite monoliths are the stars of the show, but plan to spend some time on the open granite cap at the top of the hill.

From the gate at the trailhead, follow the broad, rocky path as it climbs abruptly into the woods. Sweeping southeast, the path meets a stream running from a source high on the hill. You’ll traverse a wooden-plank bridge and pass a vernal pool sided with granite rubble and adorned with ferns and luxuriant moss. The trail is firmly packed, well defined, and well marked."
