Danger Island, Great Chagos Bank

It is a 2 km (1.24 m) long and flat island with a maximum width of 400 m (1,312 ft), covered with tall coconut trees.

Its name may derive from the lack of a safe anchorage, which rendered every visit to this island dangerous for the ship and crew.

[1] A dangerous reef also extends about two to three miles south by west of the island, which at times the sea breaks on.

Blair described the island at the time: "At dawn of day saw Breakers bearing NE, distant about ½ Mile, which I found at daylight to extend from Danger Island [...] It is covered with thick Wood, and a few Coconut Trees near the Centre" [emphasis in original].

[11] The 2015 expedition visited the island, landing by the same method but with less difficulty, and reported red-footed and brown Boobys and two species of crab: ghost and sally lightfoot.
