Geologists Seamounts (alternatively were named South West Hawaii Group[2]) are a cluster of seamounts in the Pacific Ocean, located mainly 100 miles (160 km) south of Oahu, Hawaii[3] and 100–200 kilometres (62–124 mi)[4] south-west from Big Island (Hawaiʻi).

[5] Clockwise from north they are named Perret, Jaggar, McCall, Pensacola, Daly, Swordfish, Cross, Washington and Ellis.

The seamounts developed during the Cretaceous,[8] about 80 million years ago, and there is no geological relationship to the neighbouring Hawaiian Islands.

[4] There is about contemporaneous timing with the formation of the Musicians Seamounts to the north-west of Oahu and Hawaiʻi, from the limited sampling and analysis to date.

[7] Rocks dredged from the seamounts include iron-manganese crusts, carbonates and basalts.
