Inform to your class:
Imagine you and your family are living on the Snake River Plain when the Lake Bonneville Flood takes place. You hear a great roaring sound off to the east. The ground is trembling. You are standing on a slope above the valley, and you see a great dust cloud coming toward you. A great wall of water is moving under the dust cloud. Soon the muddy water will roar past carrying whole trees and giant boulders. You will have to climb higher if you are to escape. Your brothers and sisters are scared, and so are your father and mother. What do you think? What will you do? Will you make it to high ground? What will happen then? What do you see as the flood passes? Rewrite this story and make it your own. Include some illustrations in crayon, pencil or ink.
