Molly sent the photos from a sunny Saturday sighting at Jack Block Park, noting: “Looks like E32 firefighters were doing diving training at Jack Block Park. They kept having one of the firefighters throw the cone into the water and the diver would run into the water and find it as quickly as possible, and then swim back to shore as well. It was awesome to watch (my 3-year-old wanted to watch them all day).”

We don’t have official information on exactly what kind of training/practicing was happening there – but we do know some SFD firefighters are trained as Rescue Swimmers (this Seattle Channel video shows what that program’s all about).
