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.
Catacomb Hill
Catacomb Hill () is a prominent rock peak, high, on the ridge that borders the east side of the head of Blue Glacier, in Victoria Land. The New Zealand Blue Glacier Party of the Commonwealth Trans-Antarctic Expedition (1956–58) established a survey station on its summit in December 1957. They gave it this descriptive name from the spectacular cavernous weathering occurring in the granite of the peak, suggestive of catacombs.
