Caption:Climbers descending from the summit of Mount Spurr are skiing directly over what a few months later would begin developing into a large ice cauldron. The surface of the entire lower half of the photo would eventually disappear. The rock outcrop in the upper right, immediately below the Spurr summit, was reported to be issuing sulfurous steam, from holes as well as from ice tubes. The climbers also reported hearing "gurgling" in the crack/crevasse below the outcrop.

Caption:This image of submarine topography shows a previously unknown volcano mapped by Jennifer Reynolds (UAF School of Fisheries and Ocean Sciences), during an oceanographic cruise in 2003 funded by the North Pacific Research Board. The purpose of the cruise was to create seafloor maps for studies of deep-water coral habitat. The 1900-ft tall volcano has been named Amchixtam Chaxsxii (Am'chik-tam Chakh-skiee), a name in the Atka dialect of the Unangan language suggested by the local Aleut community. The discovery of a previously unknown volcano in the Aleutian arc illustrates the extent to which basic exploration in the Aleutian is needed.

Caption:Many of the islands of the Aleutians are made up of an unusual geologic formation called columnar basalt. These formations are formed by the cooling of igneous materials. The Aleutians are part of the Pacific "Rim of Fire", made up of numerous volcanoes and geologically active landforms. In this image, biologists with the Alaska Maritime National Wildlife Refuge, explore a sea cave.
