The Malaspina Glacier nearly reaches sea level at Sitkagi Bluffs on the Gulf of Alaska. Surface altitudes range from about 25 m. at the outer margin to about 600 m. at the lower end of the Seward Glacier, its main tributary. Only satellite images can provide a complete overview of the Malaspina Glacier because of its large area. Contorted moraines on a glacier are an indication of surge behavior. The contorted moraines of the eastern edge of the central lobe and the medial moraines along the boundary with the smaller eastern lobe are clearly shown.
Contorted moraines are also visible on the western lobe.
