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.
Blue Hill, Saint Helena
Terrain in the district is quite varied with steep ridges and a limited amount of flat ground, as befits the island's volcanic origin. Blue Hill's main settlement, with the location of the community centre, is Blue Hill Village. The district also includes the settlements of Barren Ground, Head o' Wain, and Thompson's Wood, together with a few scattered cottages.
