Contest #722: the TANK Centre for the Sonic Arts, Rangely, CO, US

This week was a visit to western Colorado in the US and, to be more specific, the Tank Centre for the Sonic Arts in Rangely.

Constructed around 1940 as a railroad water-treatment facility, this seven-story Corten steel water tank was moved to Rangely in the mid-1960s for use as part of a fire-suppression system for the local utility company. The plan was never realized, though, as the underlying shale proved unable to support the weight of the filled tank. So it remained empty. However, the bed of gravel upon which the tank was placed bowed its floor into a gentle parabola, giving it an extraordinary internal acoustical resonance. has all the details on why there is a Sonic Centre in a huge tank.
