The mobilization began after 1 ka, was episodic, and ended at some as yet undetermined time prior to the latter part of the nineteenth century. Given that climate-model simulations suggest only slight variation in average surface temperature and annual precipitation in this region during the past 1000 yr, this part of the Great Plains evidently is near the threshold of widespread eolian sand transport under the present climate.
