On April 14, 1935, known as "Black Sunday", 20 of the worst "black blizzards" occurred across the entire sweep of the Great Plains, from Canada south to Texas. The dust storms caused extensive damage and appeared to turn the day to night; witnesses reported that they could not see five feet in front of them at certain points. Denver-based Associated Press reporter Robert E. Geiger happened to be in Boise City, Oklahoma, that day. His story about Black Sunday marked the first appearance of the term "Dust Bowl"; it was coined by Edward Stanley, Kansas City news editor of the Associated Press, while rewriting Geiger's news story.
