The Geological Society of Maine annually organizes field trips over a summer weekend that are usually attended by 50 or more people. Locations have included Mt. Desert Island, the western mountains in Bethel, Aroostook County, and southern coastal Maine.

Because of the coronavirus, a group field trip was not possible for this summer, so a new, unique approach has been developed that will allow society members and the general public to visit any of the selected 100 sites of geologic interest across the state. Depending on the site, visitors can see rock formations, unique landforms, or see how Mainers mined granite or gemstones across the state. Many of the sites are child-friendly.

Some of these sites are also potential “Geosites” for the aspiring Coastal Maine Geopark, a new community project for fostering awareness and place-based education about the geoheritage of coastal Maine. Those interested in visiting these geologic sites  can go to for more information, an interactive map that shows the sites, and a link to a description and photos.
