Join us for a spring exploration of the geology of the Ossipee Mountains, a world famous example of a ring dike. The exploration will showcase ancient lava flows such as basalt columns and look at the different types of bedrock that are concentrically layered within the Ossipee ring dike. The planned hike is 4.5 miles RT; most of the hiking will be on graded carriage roads but there is some elevation gain, so please wear sturdy footwear. Participants should also bring plenty of water, snacks and a lunch.
