Which of the following mountains is not a volcano in the Cascades? a. Mount McKinley c. Mount Hood b. Mount Saint Helens d. Mount Shasta

Well it is McKinley, for two reasons.

One, it is not a volcano, so that automatically rules it out.

And two, it is in Alaska, which is not even in the Cascade Range, which runs from southern B. C. (technically) to northern California.

Hood, St. Helens, and Shasta are all volcanoes within the Cascade Range.
