Discovering Geological History Lessons in Manchester, Massachusetts
While descending a hill along the wooded one-mile trail loop at Agassiz Rock Reservation, you obtain a glimpse of a very, very large boulder. “That's a 'glacial erratic',” I inform my sister as we follow my spotted mutt down the hill to the monolith nestled between the trees. During the 1800s, Louis Agassiz of Harvard University often visited the site, pondering several geologic theories. The accepted notion: as glaciers retreated, large rocks were left behind. The site certainly proved useful to the advancement of science, but now also serves anyone looking for a new outdoor adventure quite nicely.
