Description :
A 9.4 m ice core and meltwater were collected in 1995 and 1996 at the glacigenic Galena Creek rock glacier in Wyoming's Absaroka Mountains. The results of the analyses are compared to those from the ice core and meltwater at the Upper Fremont Glacier to better determine the origin and relative age of the Galena Creek meltwater and ice core. The meltwater from the Galena Creek rock glacier is composed primarily of melted surface snow and rain water rather than melted glacier ice, supporting previous estimates of slow ablation rates beneath the surface debris of the rock glacier.
