Blue Ridge Fan Dating



Extremely large boulders crop out on some alluvial fans in the southern Appalachians. On one such fan, we sampled many boulders from areas with different degrees of soil development. The model 10-Be ages of these boulders show little spatial coherence and no relationship to geomorphic position or meteoric 10-Be content of the underlying soils. From these observations, we conclude that the boulders were delivered to the fan with significant inheritance and that they remain in place for millennia as rare fan aggradation events build soils around them.
