Data release for cosmogenic beryllium-10 exposure ages of boulders deposited on moraines in the southern Sawatch and Sangre de Cristo Mountains, southern Colorado

April 7, 2022

This report summarizes the geochronologic results from boulders deposited on glacial moraines in the southern Sawatch and Sangre de Cristo Mountains of south-central Colorado. Within this report are detailed the methodology used to collect samples of whole rock, determine the concentrations of cosmogenic beryllium 10 in purified quartz isolated from those samples, and use those nuclide concentrations to calculate surface exposure ages. This report should be used as supplementary material for any publication(s) that uses the nuclide concentrations and/or ages reported herein. This version supersedes all previous age estimates and reports.
