Detroit Seamount, which was formed around 76 million years ago, is one of the oldest seamounts of the Hawaiian-Emperor seamount chain (Meiji Seamount is the oldest, at 82 million years). It lies near the northernmost end of the chain and is south of Aleutian Islands (near Russia), at 51°28.80′N 167°36′E / 51.48000°N 167.600°E / 51.48000; 167.600Coordinates: 51°28.80′N 167°36′E / 51.48000°N 167.600°E / 51.48000; 167.600 It is a seamount in the chain, located north of the hinge of the "V" in the image at right.
Detroit Seamount is one of the few seamounts to break the naming scheme of the Emperor seamounts, which are named mostly after emperors or empresses of the Kofun period of Japanese history. It is instead named after the light cruiser USS Detroit.
The Detroit Seamount is as big as the island of Hawaii.
