Latest eolian activity on outer Cape Cod commenced in the past 300–500 years and may reflect multiple factors including broad-scale landscape disturbance with European colonization, an increased incidence of forest fires and heightened storminess. Thus, local droughts are not associated with periods of dune movement in this mesic environment. 2.0–1.6, and 1.0 ka and also a wetter coastal climate, which suppressed the occurrence of forest fire. The timing of eolian deposition, particularly the initiation age, corresponds to documented periods of increased storminess/hurricane activity in the North Atlantic Ocean at ca. However, the four younger events are identified in three or more sites and show evidence for dune migration and sand sheet accretion. The two oldest events are documented at just one locality and thus, the pervasiveness of this eolian activity is unknown. Stratigraphic and sedimentologic observations, particularly the burial of Spodosol-like soils, and associated 14C and OSL ages that are concordant indicate at least six eolian depositional events at ca. The eolian sand depositional record for a dune field within Cape Cod National Seashore, Massachusetts is posit as a sensitive indicator of environmental disturbances in the late Holocene from a combination of factors such as hurricane/storm and forest fire occurrence, and anthropogenic activity.
