 | Joseph Thomas Pardee (1871-1960) played a key role in the Spokane Flood controversy, in which the cataclysmic flood origins of the Channeled Scabland were intensely debated during the decades of the 1920s, 1930s, 1940s, and 1950s. |
 | Pardee wrote to Bretz in 1925 suggesting that Bretz consider the draining of a glacial lake as a possible source for the cataclysmic Spokane Flood. |
 | Pardee may have been wrong in his 1922 interpretation of scabland flood bars, but his 1940 description of giant current ripples proved to be the key point for convincing skeptics of the cataclysmic flood hypothesis. |

 | Pardee discovered what he called "giant ripple marks" in an area that was once occupied by Glacial Lake Missoula. |
 | Pardee attributed this phenomenon to the sudden failure of the ice dam that impounded Glacial Lake Missoula. |
 | Pardee estimated that waters from Glacial Lake Missoula drained at a rate of 9.46 cubic miles an hour. |
