  • Geochemical and geomorphic data from dune fields in southwestern Nebraska provide new evidence that the Nebraska Sand Hills once migrated across the North and South Platte rivers and dammed the largest tributary system to the Missouri River
  • . The Lincoln County and Imperial dune fields, which lie downwind of the South Platte River, have compositions intermediate between the Nebraska Sand Hills and northeastern Colorado dunes. The most likely explanation for the intermediate composition
  • is that the Lincol County and Imperial dunes are derived in part from the Nebraska Sand Hills and in part from the South Platte River.

  • Possible sources of Peoria loess in central Nebraska have been investigated through the fingerprinting of the textural, geochemical and mineralogical characteristics of the loess and possible source sediments, with statistical comparison
  • of the textural and compositional fingerprints. The results contrast with the desert loess model proposed by Lugn (1960), and are instead consistent with the derivation of the Peoria loess in Nebraska primarily from fluvio-glacial outwash sediments carried
