Wind-traverse corrugations in Pleistocene periglacial landscapes of central Pennsylvania

Authors(s) and Affiliation(s)



Periglacial conditions beyond the Wisconsin glacial limit produced wind-transverse corrugations in east-central Pennsylvania. The corrugations are low, linear ridges typically several hundred meters long, 10-30 m wide, 3-8 m above the local slope, and are composed of matrix-supported diamictons. Their wide distribution implies that the region was treeless during the late Wisconsin maximum. Present discontinuities in these and other periglacial features suggest wasting of ice-rich fill in upland valleys, with consequent widening of stream channels and fan growth, at the end of periglacial time
