Landsat MSS scene (1970s) of the northern region.  The northern atolls and Blenheim reef are clear, as is Nelson Island and northern Great Chagos Bank.  The 10 m submerged Victory Bank (probably a drowned atoll) is seen between Salomon and Nelson Island.  Eagle, Danger and the Three Brothers are at bottom right (slightly stronger white than the clouds in the bottom left region).
