TThis data release includes measurements of properties from sedimentary cores collected from Henrys Lake in Idaho. We present a CSV with basic information about the cores (e.g., length, collection location, water depth), and three CSVs with the fallout radionuclide (FRN), particle size analysis (PSA), and radiocarbon (RC) data. It also has three child items with x-ray computed tomography (CT) scan images, line image scans, and multisensory core log (MSCL) data for the seven cores from Henry’s Lake, and magnetic susceptibility point (MSP) data for select cores.
