Rain date: Sunday April 26.  Leader/Speaker: Bruce Porter, Volunteer, Physicist, & Science Olympiad coach for the Glaciers Competition.  Learn about the geophysical events that shaped this land where the passage of glaciers left their mark on this landscape. A striking 40-foot-high ice-contact face rises just south of Hop Brook, eskers wind through these properties, and kettleholes pitthe plain. Learn more about the grand history of this unique SVT property. This program will begin at the Curtis Middle School, not the Gray Reservation parking lot.  Register for Event.  Fee: Members: Free, Non-Members: $10
