Short summary
Late Pleistocene Yedoma deposits of Siberia and Alaska are prone to degradation with warming temperatures. Multimodal grain-size distributions of >700 samples indicate varieties of sediment production, transport, and deposition. These processes were disentangled using robust endmember modeling analysis. Nine robust grain-size endmembers characterize these deposits. The data set was finally classified using cluster analysis. The polygenetic Yedoma origin is proved.
