W.S. Kohl Barn - Credit: Wikimedia Commons
The W.S. Kohl Barn near Richfield, Idaho, United States, is a lava rock barn built in c. 1917, probably by skilled stonemason Jack Oughton and by Sandy Reed. Its design appears to be that of a plan advertised by the Gem State Lumber Company of Richfield, and its approximate date of construction is determined by record of farmer W.S. Kohl taking out a mortgage for it in 1917. with Read more on Wikipedia
