Stack Stalk looks like an old-fashioned barber’s pole. It is a tall fixture with a beautiful plaque explaining it. Watch out for bicycles when observing. The thin posture of this artwork might be best represented in portrait mode when taking a photograph of it. Seating near it is comparatively far, but that is somewhat compensated by the beautiful simplicity of Stack Stalk. Try seeing it next time you trek the Portland Escapade.
