LiDAR data for Unalakleet, Alaska, collected in October 27, 2005

This report is a summary of a LiDAR data collection over the community of Unalakleet, in the Norton Sound region of Alaska. The original data were collected on October 27, 2005 by AeroMetric, Inc., under contract by Rodney P. Kinney and Associates, Inc. The complete, classified LiDAR dataset was purchased by the State of Alaska Division of Geological & Geophysical Surveys in 2013 in support of coastal vulnerability mapping efforts. For the purposes of open access to LiDAR datasets in coastal regions of Alaska, this collection is being released as a Raw Data File with an open end-user license.

Major-oxide and trace-element geochemical data from rocks collected near Panorama Mountain, Mile 104 Seward Highway, Crow Pass, and Whittier, Alaska

In conjunction with hosting field trips for the Association of American State Geologists 2016 annual meeting in Girdwood, Alaska, Alaska Division of Geological & Geophysical Surveys (DGGS) staff collected rock samples and obtained geochemical analysis from several readily accessible, but relatively unstudied outcrops. Samples were collected from Turnagain Arm (mile 104 Seward Highway), Whittier, Crow Pass, and Panorama Mountain (roughly mile 217 Parks Highway). Mineralized samples from veins and veinlets in granitic rocks from the Crow Pass and Whittier sites contain anomalous levels of gold ranging from 0.129 to 0.650 parts per million (ppm). Although none of the samples are from areas open to mineral entry, geochemical analyses of rocks from these localities may support interpretation of regional mineral-distribution trends. The analytical data tables associated with this report are available in digital format as comma-separated value (CSV) files. Additional details about the organization of information are noted in the accompanying metadata file. All files can be downloaded from the DGGS website (http://doi.org/10.14509/29725).

High-resolution lidar data for infrastructure corridors, Tyonek Quadrangle, Alaska

In advance of design, permitting, and construction of a pipeline to deliver North Slope natural gas to out-of-state customers and Alaska communities, the Division of Geological & Geophysical Surveys (DGGS) has acquired lidar (Light Detection and Ranging) data along proposed pipeline routes, nearby areas of infrastructure, and regions where significant geologic hazards have been identified. Lidar data will serve multiple purposes, but have primarily been collected to (1) evaluate active faulting, slope instability, thaw settlement, erosion, and other engineering constraints along proposed pipeline routes, and (2) provide a base layer for the state-federal GIS database that will be used to evaluate permit applications and construction plans. The highest-hit digital surface models (DSM) represent the earth's surface with all vegetation and human-made structures included.

Digital data addendum: Analytical data and field observations from surficial geology and morphology of the Alaskan central Arctic Coastal Plain, 1981-1987

Report of Investigation 93-1A, Digital data addendum: Analytical data and field observations from surficial geology and morphology of the Alaskan central Arctic Coastal Plain, 1981-1987, presents digitized station and sample locations and identifiers, and analytical data tables for grain size, amino acid, thermoluminescence, carbon-14, palynology, microfossil, and wood identification from 1980-1987 surficial geologic field investigations along Alaska's North Slope. This data release also provides the project's scanned field notes, measured section diagrams, and laboratory observations. The study area encompassed twenty-five 1:63,360-scale quadrangles between the Colville and Hulahula rivers. The geologic mapping, analytical data, interpretations, and measured sections resulting from these investigations were published in 1993 (Rawlinson, 1993).

Fox Hills electromagnetic and magnetic airborne geophysical survey data compilation

The Fox Hills survey is one of several geophysical surveys, collectively known as the Five Spot project (Southern Dishna River, Beaver Creek, and Fox Hills surveys), located in the Iditarod-Innoko and Aniak mining districts, which is about 575 km southwest from Fairbanks, Alaska. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from September to November 2012. A total of 1538.2 line kilometers were collected covering 529.5 square kilometers for the Fox Hills survey. Line spacing was 400 meters (m). Data were collected 30 m above the ground surface from a helicopter towed sensor platform ('bird') on a 30 m long line. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/29820.

Preliminary Derivative Geologic Materials Map of the Fairbanks Mining District, Alaska

This map illustrates potential near-surface sources of geologic materials that may be useful for construction and other purposes. Field observations indicate that each geologic unit (for example, flood-plain alluvium) has a definite composition or range of composition. Therefore, the presence of material type is interpreted from the distribution of geologic units (Newberry and others, 1996 - PDF96-16). Assignment of Unified Soil Classes (Wagner, 1957) is based on visual observation and interpretation of the likely distribution of the materials; no grain-size analyses were performed. Descriptions of unconsolidated deposits are modified from Pewe and Bel (1975a-d) and Pewe and Bell (1976). This map is generalized and is not intended to show exact locations of specific materials.

Geology of the Cobblestone Creek-May Creek area, east-central Brooks Range Foothills, Alaska

Geology of the Cobblestone Creek-May Creek area, east-central Brooks Range Foothills, Alaska, Preliminary Interpretive Report 2009-5, presents a 1:63,360 scale geologic map of the Cobblestone Creek-May Creek area of the foothills of the Endicott Mountains. This map is one of a series of areas selected for detailed mapping to document important structural and stratigraphic relationships at the east-central Brooks Range mountain front. The Cobblestone Creek-May Creek area is important in delineating the stratigraphic and structural relationships in this area because, unlike the adjacent valleys of the Itkillik and Nanushuk rivers, Cobblestone and May Creeks were not glaciated during the Pleistocene, and thus bedrock exposures are generally more continuous. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/19661.

Historically active volcanoes of Alaska

This data lists the historically active volcanoes of Alaska and the year of the last major eruptive event. The volcanoes listed meet at least one of the following criteria since 1700 CE: (1) documented, unquestioned eruption, or (2) a strongly suspected eruption, often an eruption documented in the historical account with very little information (current geologic knowledge must not contradict the eruption account), or (3) persistent (usually on the order of decades, but certainly longer than several months) fumaroles, with temperatures (where measured) within ~10 degrees C of the boiling point, or (4) significant, measured, volcanic-related, non-eruptive deformation, (5) documented earthquake swarm with strongly suspected volcanic cause. For the purposes of this dataset a major eruptive event is considered to be one in which juvenile lava erupt as a lava flow or dome or as an explosive column reaching an altitude of several thousand meters above the vent.
