Developing A Tree-Ring Chronology For Reconstructing Past Climate Conditions: Coral Pink Sand Dunes, Ut, Amy L. Cutter
Developing A Tree-Ring Chronology For Reconstructing Past Climate Conditions: Coral Pink Sand Dunes, Ut, Amy L. Cutter
McNair Scholars Research Journal
The Coral Pink Sand Dunes (CPSD) is one of the largest active dune fields in the Grand Staircase of the Colorado Plateau. A disjunct stand of ponderosa pine (Pinus ponderosa) seemingly thrives within the dune field. The presence of a multiple-aged stand suggests the site has experienced varied climatic conditions since becoming established. Other geomorphic systems in the region (e.g., arroyos) indicate sensitivity to small climate fluctuations; perhaps the dunes are similarly sensitive, leading to the question—could the trees be used to reconstruct past climate, and could that reconstruction be used to model dune activity with climate variability. The climate-growth …
