Abstract

The enigmatic DeKalbmounds in north-central Illinois, United States, are oval, inactive hillocks of Wisconsinan age. Different origins have been proposed for the DeKalb mound fied but the only previous in-depth study identified them as pingo remnants, presumably due to the degradation of significant ground ice and permafrost. In this study, the DeKalb mounds are presumed to have developed from an intricate set of glacial dead-ice and mass movement processes. This reinterpretation reflects a range of either discontinuous permafrost or negative permafrost within the paleoenvironment
