The first settlements in the area were two forts built in 1856 during the Puget Sound War to protect future settlers against possible uprisings by the native population. Fort Patterson, a few miles downstream, and Fort Tilton, a few miles upstream, were built with the help of Indians led by Chief Patkanim, and both abandoned within 2 years after interactions with the local tribes remained peaceful. A historical marker can be found north of Fall City on the Fish Hatchery Road where Fort Tilton once stood.
