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 Line (TRAX)
Beyond East 10600 South, the Blue Line heads north-northwest until it reaches Sandy Civic Center (the former southern terminus of the Blue Line, until August 18, 2013). This station is several blocks east of Sandy City Hall and the South Towne Center Mall. The Porter Rockwell Trail runs by the east side of this station and, as the trail heads north, it crosses over to the west of the Blue Line tracks at East 10000 South/East 9800 South and then runs north parallel to the Blue Line until it ends at East 8530 South. From Sandy Civic Center, the Blue Line heads north, crossing East 10000 South/East 9800 South (Sego Lily Drive) and, while running along the west side of South 170 East, passing the east side of both Jordan High School and the South Towne Exposition Center. Just after crossing East 9400 South the Blue Line reaches an infill station, Sandy Expo, which provides service to Rio Tinto Stadium in addition to the South Towne Exposition Center.
