This dataset consists of sample descriptions and radiocarbon age data from coastal environments on Montague Island, Alaska, analyzed at the National Ocean Sciences Accelerator Mass Spectrometry Facility.
This is a child item of the USGS Data Release: https://doi.org/10.5066/F7X63KF2 This dataset provides shapefiles and tabular data representing river channel geometries measured on photogrammetric imagery and extracted from a photogrammetric digital elevation model (acquired August 2021) along the Totatlanika River in central Alaska.

This data release contains two vector polygon shapefile datasets that delineate footprints of land surface disturbance and waste that may represent potential above-ground resources resulting from past mining in Alaska. These footprints were mapped on 2023 World Imagery at the location of currently inactive Alaska Resource Data File sites of past mining production.

This data release includes three tables containing cosmogenic beryllium-10 and aluminum-26 concentrations and related data from samples collected at four sites in central Alaska in 2020, prepared in 2022 at the University of Vermont (UVM), and measured at the Purdue Rare Isotope Measurement lab (PRIME) in 2022. The file "burialAge_siteLocations_centralAK_bender.csv" contains site locations in the NAD83 reference frame, and burial ages computed from raw data contained in the other files. All files are linked by the site_id_short field.
