Milligan's main significance lies in its being the location of the lowest recorded temperature in Ohio history, -39º Fahrenheit. This temperature was recorded at a United States Weather Bureau station on February 10, 1899, during the Great Blizzard of 1899, when the entire state experienced bitterly cold weather for over a week. It is believed that Milligan is so cold because of its location within the valley of the Moxahala Creek, into which cold air flows from the surrounding hills.[1]
