Iliamna Volcano, Alaska, USA

Iliamna Volcano sits by the side of Cook Inlet in southern Alaska right across from the town of Homer, quietly fuming. Its rugged cone is mostly covered with snow and ice and is deeply dissected by glaciers, a sign that erosion is wearing it down faster than eruptions are building it. Some fumaroles high on Iliamna's flanks emit occasional vapors, but its last proper eruption appears to have happened 300 years ago. Still, a few deep rumblings have been monitored in the hot spaces beneath, and Iliamna is closely watched by the Alaska Volcano Observatory, which maintains this page about it.
