Glacial isostatic adjustment directed incision of the Channeled Scabland by Ice Age megafloods [Earth, Atmospheric, and Planetary Sciences]

During the last deglaciation, dozens of glacial outburst floods—among the largest known floods on Earth—scoured the Channeled Scabland landscape of eastern Washington. Over this same period, deformation of the Earth’s crust in response to the growth and decay of ice sheets changed the topography by hundreds of meters. Here, we...
