Summary
Between 27 and 11 kyr ago, during the last major (Naptowne) glaciation, the northwestern and western Kenai Peninsula and the Cook Inlet trough were covered by ice except for local nunataks and small refugia, like the Caribou Hills. Landforms related to four glacial stades are recognized and paleogeographic maps document ice limits, drainage systems, glacial-impounded lakes, and glaciomarine terraces. Numerous multidisciplinary studies of glacial, vegetation, and insect histories document Holocene climatic changes.

To describe a wide variety of landforms and related processes, including glaciated valleys, massive rock failures, moraines, lake deposits and shorelines features, diversion channels, outwash fans and terraces, braid deltas and braidplains, glaciomarine deposits and coastal terraces, volcanoes, estuarine deposits and effects of land-level change, coastal-bluff stratigraphy, modern beach features, and tsunami hazards.
