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.)
