Description :
Eolian activity had begun in the Ferris-Lost Soldier area by at least ca. 9,950 to 10,330 years b.p. Major depositional intervals (indicating widespread Ferris dune activity) correlate with two radiocarbon-dated periods of drought. The first occurred between ca. 7,660 and 6,460 years b.p.| the second occurred following ca. 6,460 years b.p. (and lasted until ca. 5,500 years b.p.). Since the last major depositional (drought) interval, the climate in the Ferris-Lost Soldier area has moderated. Drought intervals have been short and vegetation has largely stabilized the dunes.
