Paleomagnetic evidence for repeated glacial LakeMissoula floods from sediments of the Sanpoil River valley, northeastern Washington
Recent explanations of widespread rhytmically layered sediments in eastern Washington as the result of repeated great floods from glacial LakeMissoula implicitly suggest a paleomagnetic test for validity. This work is an application
Cataclysmic late Pleistocene flooding from glacial LakeMissoula: a review
Late Wisconsin floods from glacial LakeMissoula occurred between approximately 16 and 12 ka BP. Many floods occurred| some were demonstrably cataclysmic. After resolution of the scabland's origin by cataclysmic outburst flooding from glacial Lake
Missoula, research since 1960 emphasized details of flood magnitudes frequency, routing and number. Major advances have been made in the study of low-energy, rhythmically bedded sediments that accumulated in flood slack-water areas.
The Pleistocene outburst floods from glacial LakeMissoula, known as the Spokane Floods, released as much as 2 184 km of water and produced the greatest known floods of the geologic past. A computer simulation model for these floods that is based
During the last glaciation the Cordilleran Ice Sheet covered the upper course of the Columbia River and part of the Columbia Plateau. A large ice-dammed lake called Glacial LakeMissoula was formed in Montana, when an ice lobe plugged a valley
in Idaho. Once the water level in the ice lake had risen to a certain height the ice dam collapsed and draining of the ice lake resulted in a gigantic flood. A new ice dam was then formed, and after some time a further catastrophic flood occurred. It has

At Sheep Mountain Bog, near Missoula, Montana a late-glacial tephra, that probably fell in late summer, is preserved in lake deposits. Sediment surrunding the ash was 14C dated to about 11,200 yr B.P. Electron-microprobe analyses of the volcanic
