STATUS: Still standing
Located in Placer County, California, Iowa Hill was filled with gold miners after a piece was found in 1853. The town has burned down on three different occasions. In its day, it had grocery stores, a brewery, a soda factory, hardware stores, and hotels.
Today, it is a historical landmark with few residents, who have been said to be very friendly. Signs in the town forbid smoking or having an open flame, as there are believed to be flammable gasses in the air that led to the three fires in the town.
