"Black Cow" Root Beer Float Created on August 19, 1893 On August 19, 1893, Frank J. Wisner, owner of Cripple Creek Brewing, served the first root beer float in Cripple Creek, Colorado. Inspired by the moonlit view of snowcapped Cow Mountain, he added a scoop of ice cream to his Myers Avenue Red root beer and began serving it as the "Black Cow Mountain." Kids loved it and shortened the name to "Black Cow." As Paul Harvey might say, "Now you know the rest of the story." And as a librarian might say, "Stop in and check out some pretty sweet books at your library!"
