Aeolian and drainage classification data for various archaeological sites in Grand Canyon National Park along the Colorado River from 1973 to 2022

These data were compiled to assess the risk of erosion to archaeological site preservation. The objective of the study is to evaluate changes in archaeological site condition over time as a function of two geomorphology based conceptual models that evaluate the extent to which sites are potentially affected by 1) erosion from gullies, and 2) wind-driven (aeolian) supply of river-sourced sand, respectively. These data represent the results of two classification metrics, based on the two conceptual models, applied to a population of 362 archaeological sites over multiple decades. Both conceptual models numerically rank geomorphic conditions with class values of 1 representing the best potential for archaeological...
