Well-preserved stabilized parabolic dunes occur in the Albany Pine Bush, New York State, northeastern USA. This integrated study examines the morphology, grain mineralogy and micromorphology, stratigraphy, and chronology of the “Overlook Dune” in the preserve. The bulk of evidence indicates that the distance and time of dune transport was very short, and that the dune was active for about 500 years, between 12,500 and 11,000 years ago. The well-preserved morphology of dunes, and an absence of paleosols and stratigraphic truncations, all support dune stability throughout the Holocene, even with recurrent wildfire to which the local ecology has adapted.  

Stephen Wolfe is a research scientist with the Geological Survey of Canada. He has studied permafrost and cold-climate processes for over 30 years and has published more than 50 peer-reviewed papers on eolian processes in North America. His eolian research includes drought reconstructions from sand dunes, late Pleistocene dune fields in permafrost landscapes, and changing wind patterns during deglaciation. He has also investigated the origins of wind-oriented lakes in Arctic Canada and desert-type dunes in western Canada. His current research is focused on investigating the distribution and activity of sand dunes in Northeastern North America.

Suitable for tweens, teens and adults.
