Geologic evidence indicates that slab window subduction modified the forearc basin of the Chugach-Prince William terrane (CPW), producing marine basalts that are anomalously close to the trench and are interbedded and structurally interleaved with the Paleocene flysch of the CPW. A similar model is...
