This report summarizes the cosmogenic beryllium-10 (10Be) geochronologic results from boulders deposited on moraines in the Stura Valley of the Maritime Alps, the southwestern most extent of the European Alpine mountain chain, northwestern Italy. Within this report are detailed the methodologies used to collect samples of whole rock, determine the concentrations of cosmogenic 10Be 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.

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.

This report summarizes the age-dating results from two alluvial fan surfaces (map units Qyf2 and Qyf3) that are broken by strands of the Cucamonga Fault, in southern California, at Day Canyon and Etiwanda Canyon. Within this report are detailed the methodology used to collect samples of rock and sediment, determine concentrations of cosmogenic beryllium-10 in purified quartz isolated from the samples, and use those nuclide concentrations to calculate surface exposure ages. This report should be used as the supplementary materials for any publication(s) that uses the nuclide concentrations and/or ages reported herein. This version supersedes all previous age estimates and reports.
