Button Island (Massachusetts)
Button Island is a small island in the Hingham Bay area of the Boston Harbor Islands National Recreation Area. It is part of the Town of Hingham. The island has a permanent size of under 1-acre (4,000 m2), plus an intertidal zone of a further 116 acres (0.47 km2). It is composed of a massing of glacial till which rises to a height of 10 feet (3.0 m) above sea level. The island is managed by the town of Hingham, and access is by private boat only.
The island is notable for a large oak tree, which together with several smaller oaks, cedars, and sumac cover the island. Shrub species such as bayberry and dewberry can also be found. Grasses and sea-lavender populate the inter-tidal zone.
