MMGM Rock Garden

Maine's Most Unique Geological Exhibit

MMGM’s Rock Garden introduces Maine’s geology with 22 truly amazing geological specimens hand-selected from around the State (and one mammoth specimen from outer space!). Each specimen has an interesting story to tell and access to this exhibit is available 24/7.

You can sponsor a specimen in the rock garden with a donation. Your name (or designee) will be displayed with the specimen. This is an enduring recognition.

The MMGM Rock Garden is featured as part of the “Maine Geologic Facts and Localities” series produced by the Maine Geological Survey. Dig deeper and access a copy of this publication here.
