Coastal Mountains nature walk: Geology of Sears Island

Event has passed

SEARS ISLAND — Coastal Mountains Nature Program, in partnership with Friends of Sears Island, presents Geology of Sears Island on Saturday, Oct. 8, from 2 - 5 p.m., at Sears Island, in Searsport.

The Coastal Mountains Nature Program is a series of monthly naturalist-led walks and talks exploring the natural history of Midcoast Maine.

Dr. Steve Norton, Professor Emeritus of Earth and Climate Sciences at the University of Maine, will lead an exploration of the past 350 million years of Midcoast geological history by exploring the rocks and sediment of Sears Island. This walk is timed to take advantage of low tide, exposing the shoreline of the island. Meet at the entrance to Sears Island at the end of the causeway in Searsport.



From downtown Searsport, drive 2 miles northeast on Route 1 to Sears Island Road (which will be on the right if driving from the town of Searsport). Continue on Sears Island Road across the causeway to the island. Park on the causeway. 

Hunting is allowed on the island so participants are suggested to wear hunter orange.


The Coastal Mountains Nature Program is hosted by Coastal Mountains Land Trust.  This program hosts walks and talks exploring the natural history of Mid-Coast Maine to educate the public about environment issues and increase opportunities for residents to explore the outdoors.


Coastal Mountains Land Trust has worked since 1986 to permanently conserve land to benefit the natural and human communities of the western Penobscot Bay. The Land Trust has protected over 12,000 acres to date, offering 50 miles of trails for public access.


The mission of the Friends of Sears Island (FOSI) is to support permanent protection of Sears Island’s environmental and cultural resources; preserve its marine, shoreland, and forest ecosystems; and encourage educational and low-impact recreational uses of the island.
