Photoscans and computed tomography of sediment cores from Henrys Lake, Idaho

Transect of sediment cores from Henrys Lake, Idaho. (a) High‐resolution photoscans and computed tomography (CT) of each core correspond to the location tie line. White line on CT represents gamma ray attenuation bulk density (g/cc). Mapped facies are right of each correspondent core. Shades of gray represent background sedimentation and the event deposit by orange. Numbers 1–4 represent background sediment subfacies. HP: herbaceous peat, FL: fluviolacustrine facies, E: event deposit. Yellow rectangles represent sediment sample locations for radiocarbon dating (R1‐3). (b) Bathymetric map of Henrys Lake from data collected by the Idaho National Lab ca. 1990 with a contour interval (CI) of 0.6 m. Thick contour line shows the estimated shoreline prior to dam construction. Black triangles point to primary inlets; DC‐ Duck Creek and TC‐ Targhee Creek.  Figure from Nicovich et al., 2024 (https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2024GL110889).
