Sculpted, Scoured & Scraped: An Eastern Washington Geology Experience
|
3rd-6th Grades 17 million years ago, sheets of volcanic lava flowed from giant cracks in the earth near the Washington/Oregon/ Idaho border and covered eastern Washington. Ice Age glaciers covered much of the northern part of Washington and blocked rivers forming giant lakes. Glacial Lake Missoula in Montana, ruptured its ice dam and unleashed some of the largest floods that mankind has ever known onto the plains of eastern Washington. The trunk comes with videos, visual aids, rock samples, equipment as well as a curriculum guide that addresses the geologic processes central to the history of eastern Washington. |

Fire is a natural part of Lake Roosevelt's dry forest and desert environment. Park fire fighters, to protect nearby landowners, manage the forest by extinguishing any wildfire, as well as thin, pile up, and burn excess vegetation in winter. Prescribed fires may be lit to burn what is left.
