The volcano's glaciers have extensively altered its profile, cutting, deep and creating steep cliffs and cirques.[5] A ridge extends 5 kilometres (3.1 mi) south from the main body of the mountain, with North Twin and South Twin peaks along its length. There is no summit crater, only a zone of fumaroles just south of the summit at the top of large collapse zone at the head of Red Glacier, which exposes a cross section of the mountain.[6]
Major glaciers radiate from the summit of Iliamna,[6] including Red Glacier, Tuxedni Glacier, Lateral Glacier and Umbrella Glacier.
Iliamna was first ascended in 1959.[2] It was designated a National Natural Landmark in 1976.[9]
