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 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.HistoryKnown to the Mattabeseck Indians as Kuttomquosh, "the beautiful sea rocks," they consist of a jumble of granite rocks, ledges and outcroppings resulting from glaciation, numbering between 100 and 365 depending on where the line is drawn between an island and a mere rock. The islands serve as a rest stop for migrating seals.The first European to discover the islands was Adrian Block in 1614. Legend says that Captain Kidd buried his treasure here, causing intermittent interest among treasure hunters who believe they have unearthed a clue to its location, although more interest is generally paid to Gardiners Island, 30 miles (48 km) away.
