Abstract

Accounts published by early explorers indicate that at least parts of dune fields in Nebraska, Colorado, Kansas, New Mexico, and Texas were active in the 19th century. Based of an index of dune mobility and a regional tree-ring record, the probable cases for these periods of greater eolian activity are droughts, accompanied by higher temperatures, which greatly lowered the precitation-to-evapotranspiration ratio and diminished the cover of stabilizing vegetation. Dune fields in the Great Plains are extremely sensitive to climate change and the potential for their reactivation in the future is high
