Description
Unimak 5270 is an unnamed Pleistocene volcanic center between Isanotski and Roundtop on Unimak Island. Observations made from a helicopter during multiple flybys (during Shishaldin fieldwork) show that lava flows dip radially away from the summit, thus Unimak 5270 was a separate vent/volcano (from Chris Nye, 2008, written commun.)Name Origin
"Unimak 5270" is an informal name, given because the highest peak of this volcanic center is 5270 feet in elevation.
