Under which president administration were thousands of african americans fired from civil service positions?

Both Theodore Roosevelt, and Widow Wilson, Aberham Lincoln was also against racism

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.
