Sand Key Reef & Lighthouse Wiki
Sand Key Light is a lighthouse 6 nautical miles (11 km; 6.9 mi) southwest of Key West, Florida, between Sand Key Channel and Rock Key Channel, two of the channels into Key West, on a reef intermittently covered by sand.
At times the key has been substantial enough to have trees, and in 1900 nine to twelve thousand terns nested on the island. At other times the island has been washed away completely.
Sand Key is a coral reef located within the Florida Keys National Marine Sanctuary. It lies to the southwest of Key West, within the Key West National Wildlife Refuge. This reef is within a Sanctuary Preservation Area (SPA).
The Sand Key Light was built on the key. The reef lies to the south of the light. (via Wikipedia)
