2023 Arctic Strategic Transportation and Resources (ASTAR) project geotechnical data and sample descriptions: Point Lay, North Slope, Alaska

Description

2023 Arctic Strategic Transportation and Resources (ASTAR) project geotechnical data and sample descriptions: Point Lay, North Slope, Alaska, Raw Data File 2026-2, presents geotechnical descriptions of 160 sediment and material samples collected between July 24 and August 5, 2023, in the Point Lay and Wainwright 1:250,000 scale quadrangles in northwestern Alaska, across an approximately 21,187 km2 (8,180 mi2) area. Geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) and ASRC Consulting & Environmental Services, LLC (ACES) documented the character of bedrock and unconsolidated surface materials and collected sediment samples to investigate the distribution of landforms and shallow subsurface rock and sediment in the region. This work was completed in support of a sand and gravel resource assessment for the Arctic Strategic Transportation and Resources (ASTAR) project. Sample descriptions, presented here, constitute one of two data products produced for the 2023 field season and support a reconnaissance-level evaluation of potential construction material resources on the North Slope. The dataset complements Hubbard and others (2026), which provides field station locations and site descriptions for the 478 stations visited during the same campaign. Because information on local construction material resources is limited, sample descriptions offer useful insight into the quality, quantity, and distribution of potential material sources for community planning and land use decision making. These data are provided as a Raw Data File under an open end-user license and are available on the DGGS website: http://doi.org/10.14509/31806.
