The Thimble Islands is an archipelago consisting of small islands in Long Island Sound, located in and around the harbor of Stony Creek in the southeast corner of Branford, Connecticut. The islands are under the jurisdiction of the United States with security provided by the town of Branford police and the US Coast Guard.
The archipelago of islands made up of Stony Creek pink granite bedrock were once the tops of hills prior to the last ice age. As a result, the Thimble Islands are much more stable than most other islands in Long Island Sound, which are terminal moraines of rubble deposited by retreating glaciers.[citation needed]
