Water is dripping onto this outdoor drum in the drum courtyard of the Cedar River Watershed Education Center at Rattlesnake Lake. At the center of the image a splash in progress. Several drums were played by spurts of water. I presume the flow is controlled by a computer, as the pattern of spurts changed periodically.

More information about these rain drums is at the website of artist Dan Corson.

I visited the eduction center during a trike ride on the Snoqualmie Valley Trail.
