δ18O variations at Andrews Meadow
By Geosciences and Environmental Change Science Center
March 2024 (approx.)
Detailed Description
The sediment record pulled from Yellow Lake (green) and Bison Lake (blue) starts in the Holocene. The record pulled from the trees in Andrews Meadow shows the Modern period. Both show wet and dry extremes over the years.
A major finding is that the sediment record directly compares with the tree-rings that are shown to track historic wet and dry extremes. This confirms the method’s feasibility for linking sediment records to discharge.
Sources/Usage
Used under STM Permissions Guidelines "fair use". Originally published in The Holocene (a Sage Journal): "Testing tree-ring cellulose δ18O with water isotopes for Holocene lake δ18O interpretations in the central Rocky Mountains USA.".

Historic lows in Colorado River reservoirs emphasize the critical role of snowpack. This research further refines understanding of precipitation in the Colorado River Basin, a critical water resource.
