Eolian Sediments in the Greater Platte River Basins, Great Plains
The Greater Platte River Basins occupies a large part of the Great Plains of central North America. It is a semiarid region and like most semiarid regions, experiences a wide range of variability in year-to-year precipitation. This makes the region's geomorphic systems highly sensitive to climate changes. Much of the Greater Platte River Basins is covered with eolian sediments (dune sand, sheet...
