High-resolution seismic-reflection profiles illustrate the geometry and seismic characteristics of sedimentary facies within the Muir Inlet morainal bank complex. The interpreted sedimentary facies include a grounding-line fan, two stratified ridges, debris flow/turbidity current deposits and a field of push ridges (Figs. 1 and 2). This morainal bank complex was deposited on a shallow sill at the mouth of Muir Inlet, a fjord in Glacier Bay, between 1860 A.D. and 1899 A.D. during retreat from the Little Ice Age maximum. Profiles of the morainal bank complex were collected with a single channel 1.2 kJ uniboom (600 and 1700 Hz) system by the U.S. Geological Survey, Menlo Park, CA.
