Station 19AAJRS024. This peninsula on the east side of Atka is composed of a base of ~20 meters of glacial diamict with poorly sorted clasts of up to 1-meter-sized faceted boulders in a sandy matrix. More than 6 meters of layered tephras and soils cap this diamict. In other places along the shoreline, this diamict is underlain by layered lavas. Coombs and Schaefer have described the tephra section in detail and collected both tephra and soil samples.
