Abstract
As the result of geologic investigations and shallow exploratory drilling, a potentially developable warm water artesian aquifer was found in shallow unconsolidated deposits near the Summer Bay warm spring, which is located near the Unalaska community on Unalaska Island. The actual water source for the warm spring and the warm water aquifer is not well understood, but the source is probably directly related to deep N. 50°W. fractures. Magma is suspected to exist in such fractures at great depths in this region.
