Taken at Jamison Square in the Pearl district of Portland on a hot day a couple of weeks ago... From Wikipedia: "The park was designed by PWP Landscape Architecture. The park was initially designed as an outdoor art gallery, with square rocks and steps at the center, but no water. Water, running at random times over the rock, was added to keep skateboarding teenagers from using them. The water on the rocks ended up turning the park into an urban beach, attracting children and families who use it as a wading pool, with the intermittent nature making it a "manmade tidal pool", also called "the community pond" by locals. A wooden boardwalk, made of ipe, connects Jamison Park to Tanner Springs Park, two blocks away, and is intended to eventually connect to the Willamette River." Please zoom.
