Abstract

Buried soils in sand dunes on Cape Cod, Massachusetts, and near Glen Haven, Michigan, contain layers of fine-textured material. Field relations of the strata demonstrate that the material was wind-laid. The size, shape, and specific gravity of the fine material indicate that it was transported in suspension by wind. Occurrence of plant remains in all of the fine-textured layers, and the fact that fine material is accumulating in forest stands at the present time points to the important role that vegetation plays in the accumulation of wind-blown material, even in humid regions. Wind-blown material accumulates in areas supporting vegetation as a result of deposition due to decreased wind velocity and as a result of preservation of the deposits from wind and water erosion.
