| Abstract: | Ice-wedge casts, relict sand wedges, ventifacts, deflation surfaces and aligned landforms record permafrost around the margin of ice sheet from Montana to Indiana. From Montana to north-east Nebraska, north-west winds were compressed into narrowing zone with increasing velocity, keeping upland areas free of snow so that permafrost developed and yardangs formed. Sand that was deflated from desiccated snowfree ridges dropped into thermal contraction cracks, forming sand wedges. Eastward, strong winds deflated soils to produce Iowan erosion surface, leaving paha as ridges. Permafrost may have been continuous in Wisconsin and Minnesota between 23 and 18 ka, but was discontinuous or sporadic in Illinois and Indiana. |
