Seismic refraction profiles near Kodiak, Alaska have provided data for construction of a cross‐section showing the crustal structure from the east end of Kodiak Island across the continental terrace and slope to the Aleutian Trench (Figures 1 and 2). Five reversed refraction stations and one unreversed station were available (Table 1); interpretation was aided by access to reflection profiles which cross the refraction lines (Shor, 1972).
