| Ring-necked Ducks are uncommon as breeders in low-elevation wetlands in eastern Washington, but rare east of the channeled scablands. |
|
| What did Mr. Bretz conclude from observing the channeled scablands? |
|
| Examples can be seen in the flood regions result from glacial Lake Missoula, which created the channeled scablands in the Columbia Basin region of eastern Washington. |
|
| Bretz presented a paper suggesting that the Channeled Scablands in eastern Washington were eroded catastrophically. |
|
| He named the Channeled Scablands, with its catastrophically water-carved coulees, dry waterfalls, potholes and huge erratic boulders. |
|
| The Missoula Floods of Oregon and Washington states were also caused by breaking ice dams, resulting in the Channeled Scablands. |
|
| Good examples of these structures can be found in the Channeled Scablands of eastern Washington, an area heavily eroded by the Missoula Floods. |
|
| The Channeled Scablands in Southern British Columbia and Washington State is an example of a steppe region in North America outside of the Great Plains. |
