... most rapidly deforming collisional orogens in the Wrangell–St. Elias region, but this orogen is also being exhumed at some of the highest rates on Earth. The exhumation differs from most orogens, however, in that glacial and glaciofluvial erosion and deposition dominate the region. This produces...
