On Sunday, March 13, Princeton geology professor emeritus Lincoln Hollister will lead a guided walk through Herrontown Woods explaining the geological features and history of the area. If you thought the boulders were deposited by a glacier, you're in for a surprise.
The walk is at 1pm. A limited number of spots are available. Click here to sign up.
Next time you walk the yellow trail, notice how the boulders along the stream start out squarish, but become more rounded as you head up onto the ridge. These two shapes were produced in different geologic eras.
