Map units are the result of combined field observations and aerial imagery interpretation. A suite of local ground observations were collected over a two-week period in July 2011 by a helicopter-supported team of DGGS geologists and collaborators. Field investigations included soil test pits, sample collection, soil and rock description, oblique aerial photography, and documentation of landscape morphology. Purpose: According to the 2010 United States census, more than 60 percent of Alaskans reside in coastal communities. Many of these communities are exposed to a wide range of geologic hazards including erosion, landslides, wave attack, storm surge/flooding, tsunami and ivu (ice push). Since 2004, reports and recommendations from the U.S. General Accounting Office, the U.S. Army Corps of Engineers, and the Immediate Action Work Group of the Governor's Subcabinet on Climate Change have highlighted the imperiled or at-risk status of many Alaskan villages that are subject to severe flooding and erosion. In response to both existing risks and to shifts in the frequency and/or magnitude of geohazard- triggering events, including those that may be influenced by changing climate, communities throughout the state are becoming increasingly involved with mitigation or adaptation efforts in response to these natural hazards. Baseline data pertaining to local geology, coastal and oceanic processes, and historic natural hazard events are necessary to facilitate adaptation efforts. Supplemental_Information: This digital data distribution package provides shapefiles and geodatabase that portray features presented in RI 2017-5. Field names and values are organized according to the NCGMP09 - Draft Standard Format for Digital Publication of Geologic Maps, Version 1.1 by the USGS National Cooperative Geologic Mapping Program (NCGMP). This metadata file lists the table names and field names used in the geodatabase. Table and field names in the shapefiles are truncated at 10 characters. The geodatabase and selected shapefiles provide the following features: >ContactsAndFaults: Line features that depict faults and geologic contacts. >GeochronPoints: Geochronology sample location points. >MapUnitPolys: Polygons that record the distribution of mapped or interpreted geologic units. >Stations: A point file that provides location information, observations, and other data specific to each field observation station.

A suite of local ground observations were collected over a two-week period in July 2011 by a helicopter-supported team of DGGS geologists and collaborators. Field investigations included soil test pits, sample collection, soil and rock description, oblique aerial photography, and documentation of landscape morphology. Best available orthorectified aerial photographs and satellite imagery were used to interpret surficial-geologic units and delineate contacts at a scale of 1:50,000 or smaller. Organic samples were radiocarbon dated to provide constraints on the age of unconsolidated deposits and understand the sequence of depositional events.
