These data are records collected from six automated weather stations in operation between January 1, 2014 and December 31, 2015 within the Colorado River Corridor of Grand Canyon National Park and Glen Canyon National Recreation Area. Data collection locations, equipment configurations and methods follow those of the original report (OFR 2014-1247). These files are 4-minute interval data for each of the automated weather stations, tab separated by parameter (wind direction, wind speed, wind gusts, air temperature, relative humidity, barometric pressure, and rainfall). Climatic conditions during the reporting period were warm and dry early in 2014 and transitioned to average to slightly above precipitation from mid-2014...
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...
