In celebration of Great Maine Outdoor Week(end) we’ll circle Shell Pond. Periodically we’ll pause to test the temperature and pH level of the brook, springs, pond, and outlet stream as we discuss the differences we observe and how they may affect aquatic life. We'll also take in the mountain views and enjoy lunch along the way. BYOL.
