Blue Hole (Big Pine Key)
The Blue Hole is an attraction on the island of Big Pine Key in the Florida Keys. It is an abandoned rock quarry that was used for nearby road fills and Henry Flagler's Overseas Railroad. The water it contains is mostly fresh and is used by various wildlife in the area, such as birds, snakes, alligators, key deer and green iguanas. It is part of the National Key Deer Refuge.
Great Blue Hill
Great Blue Hill (called Massachusett by Native Americans) is a hill of 635 feet (194 m) located within the Blue Hills Reservation in Milton and Canton, Massachusetts 10 miles (15 km) southwest of downtown Boston. It is the highest point in Norfolk County. The modern name for the hill was given by early European explorers who, while sailing along the coastline, noticed the bluish hue of the exposed granite faces when viewed from a distance (due to Riebeckite). The Blue Hills' eastern slopes face the ocean and lie within Quincy. The area attracted quarrying for its "blue granite".
The name of the Massachusett Indian tribe and their language (and thus the name of the Bay, Colony, Commonwealth/State, etc.) derive from the Massachusett name for the hill: "massa-adchu-es-et", where "massa-" is "large", "-adchu-" is "hill", "-es-" is a diminutive suffix meaning "small", and "-et" is a locative suffix, identifying a place.
