1. Using the satellite image of southeastern Idaho and a piece of tracing paper, trace or draw as many of the major features as you can. Specifically identify and label the following features (some are already labeled to give you a frame of reference):
American Falls Reservoir
Big Lost River Valley
Big Southern Butte
Craters of the Moon
Hell's Half Acre
Idaho Falls area
Lost River Range
2. Compare the various lava flows on the plain. There are approximately four
large ones: Craters of the Moon, Hell's Half Acre, Cerro Grande and Wapi. Can
you see a difference in their color? Why is there a difference or what would
cause the difference?
3. Where does the majority of the vegetation (red) appear in the image? What is the main cause for this distribution?
4. Compare the mountain ranges to the north of the Snake River Plain to the mountain ranges to the south. What is apparently different about them as far as vegetation is concerned? If there is a difference between the north and south ranges, give a possible reason why.
5. Why is there so little out on the Snake River Plain?
6. Where do the farms that are located further out on the Snake River Plain get the water that they need to grow crops?
7. At the northeast end of the American Falls Reservoir there is a patch of white. What is it? Based on your interpretation of the white patch and distribution of vegetation, during which season of the year do you think that this image was created?
