Questions for Photo 5
1. What do you think is going on in this image? Where is the river? Look at Illustration 1. Does that help you figure out where the river went?
2. How many steam shovels can you count? Based on the size of the people in the image, how big do you think these shovels were?
3. Go back to Reading 2. How did the shovels get down into the canyon?
4. The shovels had to remove about 130 feet of soil and loose rock before they could get down to solid rock. Why do you think it was so important to do that before starting work on the dam structure itself?
