Geologic context and track-maker demographics of White Sands Study Site
Detailed Description
Left: Oxygen isotope (δ18O) data from Greenland ice core records highlighting Dansgaard-Oeschger (D-O) events 1-8. Middle: Composite stratigraphy of the human footprint layers, radiocarbon ages, and dominant hydrologic regime for sediments exposed in the trench. Filled circles denote radiocarbon samples. Trackway horizons (TH) 1-8 are shown in their correct stratigraphic positions. Right: Summary of footprint evidence on each horizon. Modified from Bennet et al. 2021.
