The Nature Explorers Lassen Volcanic Region Expedition Part 5 of 13

submitted by: thenatureexplorers

We travel to the Lassen Volcanic Region to explore this high subalpine montane region just below the tree line, made up of vast conifer forests and rocky outcroppings. Here we observed a huge array of butterflies, moths, bees, and other insects pollinating flowers to ensure their continued survival.

Cataclysms on the Columbia, the Great Missoula Floods Scott Burns Department of Geology Portland State University One of the greatest set of geological events to ever have occurred in North America was given the name, the Missoula Floods. The floods originated when an ice dam broke in upper Idaho liberating waters impounded in back of it in Montana, scouring out large sections of eastern Washington and the lower Columbia River drainage basin.
