Resolution Guyot, formerly known as Huevo, is a guyot (tablemount) in the underwater Mid-Pacific Mountains. It is a circular flat mountain, rising 500 metres (1,600 ft) above the seafloor to a depth of about 1,320 metres (4,330 ft), with a summit platform 35 kilometres (22 mi) wide. The Mid-Pacific Mountains lie west of Hawaii and northeast of the Marshall Islands, but at the time of its formation the guyot was located in the Southern Hemisphere, by a hotspot in today's French Polynesia. Plate tectonics shifted it to its present-day location, and the Easter, Marquesas, Pitcairn and Society hotspots may have been involved in the formation of Resolution Guyot. Volcanic activity has been dated to have occurred 107 to 129 million years ago and formed a volcanic island that was subsequently flattened by erosion. The platform emerged above sea level at one point before eventually drowning for reasons still unknown, with thermal subsidence lowering it further to its present depth.
