Carnation, WA

FS Thunderbolt 1000(T) - Originally installed in the 70s as a siren for the Tolt Dam, but eventually replaced by a system of analog Whelen WPS-2800s in 1993. Has been left to rot ever since. Unable to access tag on the control box due to the siren being absolutely covered in vines. Allegedly was never tested during its service. Better quality photos soon.
