The Arizona Canal dates back the 1880's and is part of the vast Salt River Project water distribution system in the Phoenix area. The canal runs 50 miles through Phoenix, Scottsdale, Glendale, Peoria and Mesa. In Scottsdale it serves as the center point for what is called the Scottsdale Waterfront. I've posted about that before here. A little bit past the Scottsdale Waterfront area, the canal runs under Scottsdale road and emerges again on the other side. Many times driving past this intersection, I've noticed the pedestrian bridge across the canal and all the bell-like structures on the side of it. I finally made a point of taking a closer look.
I really thought I'd hear some tones with the water flowing over these bells but, all I could hear was the gurgling water.
It's an interesting feature that is part of the Scottsdale Public Arts project along the canal.
