Celebrate National Root Beer Float Day (August 6) knowing the delicious beverage was invented right here in Colorado.

The root beer float was invented by Frank J. Wisner a mining and bar owner in Cripple Creek, Colo. in August 1893.

It is widely believed Wisner was inspired to create the drink when he was looking at Cow Mountain on a moonlit night and thought the snow covered peaks on the dark mountain looked like ice cream atop a dark beverage.

Wisner then went to his bar and topped his most popular soda, root beer, with vanilla ice cream calling it Black Cow Mountain. The name was later shortened to black cow and  over the years became known as the root beer float.

There are variations of the root beer float that use different flavors of ice cream, but the true black cow should always be made with root beer and vanilla ice cream.
