Over the weekend, Ballard resident Jennifer Greiner Clark documented a unique sight: a submarine was passing by Golden Gardens around midday on Saturday, headed north.

Jennifer posted the photo in the My Ballard Group, using her binoculars and her phone camera.

The sub was also seen from West Seattle — the West Seattle Blog says that Bremerton is a homeport to two submarines. The Puget Sound Naval Shipyard is based in Bremerton, which has historically been a hub for building submarines — the shipyard built seven of them during World War I.

There’s some speculation about which sub it was — there are two active subs that are based in Bremerton; the USS Seawolf (SSN-21) and USS Connecticut (SSN-22) (If you’re a pro at identifying submarines, let us know!)

Thanks to Jennifer for posting the photo!
