Castlewood Canyon State Park is a Colorado state park near Franktown, Colorado. The park retains a unique part of Colorado's history, the remains of Castlewood Canyon Dam. Visitors can still see the remnants and damage from that dam which burst in 1933. The event sent a 15-foot (5 m) wave of water all the way to downtown Denver resulting in a flood. Also contained within the park is the historic Cherry Creek Bridge.
