A Guide to the Late Quaternary History of Northern and Western Kenai Peninsula, Alaska

Reger, R.D. Sturmann, A.G. Berg, E.E. Burns, P.A.C. 2008 A Guide to the Late Quaternary History of Northern and Western Kenai Peninsula, Alaska vector digital data Guidebook GB 8 Fairbanks, Alaska - USA State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys 112 pp., 6 sheets, scale 1:63,360 http://www.dggs.dnr.state.ak.us/pubs/pubs?reqtype=citation&ID=15941 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. The layers listed below are present as ArcGIS shape files. Attribute information for the following layers (entities) is included in this metadata file under the "Entity_and_Attribute_Information" section. Each layer is listed and described in detail under its own heading starting "Entity_Type_Label."

Aerial photographs interpreted include 7-6-75 1:15,840-scale black-and-white photos, 7-7-76 1:15,840-scale color photos, August 1984 1:63,360-scale false-color infrared photos, and 6-14-98 1:12,000-scale color photos. Maps interpreted are 1:25,000-scale provisional-edition metric maps of the Kenai Quadrangle published in 1986 and 1987 and of the Seldovia Quadrangle published in 1987. Field investigations were conducted from 1976 through 2006. Data for paleogeographic arc shapefile were 'on screen' digitized from a scanned paper map compilations. Paleogeographic information was compiled on paper topographic maps with abundant control points at 1:25,000 scale and registered in ArcGis 9.2, then reduced to a layer onto a 1:63,360-scale USGS topographic base. Data are arc (line) data and do not require topologic relationships. This dataset includes geospatial information about paleogeographic linear features depicting ice limits of four glacial periods on the Kenai peninsula.
