The question is based on Figure 38-8, a digital elevation model showing the 2014 Oso, Washington, landslide along the North Fork Stillaguamish River, and color Map T-26b in the back of the Lab Manual, showing a portion of the “Mount Higgins, Washington” quadrangle (scale 1:24,000; contour interval 40 feet); this same topographic map is reproduced in black-and-white as Figure 38-14.
What will be an ideal response?
