Limalok is a guyot, an undersea volcanic mountain with a flat top, in
the southeastern Marshall Islands in the Pacific Ocean. Located at a
depth of 1,255 metres (4,117 ft) with a 636-square-kilometre
(246 sq mi) summit platform, it is joined to Mili Atoll and Knox Atoll
through a volcanic ridge. Limalok probably started as a shield volcano
built up from basaltic rocks; the Macdonald, Rarotonga, Rurutu and
Society hotspots may have been involved in its formation. A period of
erosion and flattening began around 56 million years ago. During the
Paleocene and Eocene, a carbonate platform (mostly red algae) supported
an atoll, or an atoll-like structure with reefs. The platform sank below
sea level roughly 46–50 million years ago during the Eocene, perhaps
because the equatorial area it moved through was too hot or nutrient-
rich to support the growth of a coral reef. Thermal subsidence lowered
the drowned seamount to its present depth.

Wikiquote quote of the day:
I TOOK my power in my hand And went against the world; ’T was
not so much as David had, But I was twice as bold. I aimed my pebble,
but myself Was all the one that fell. Was it Goliath was too large,
Or only I too small?
