'' Salmon Cycle Marker '' is installed at the intersection of Southwest Broadway and Jackson , just west of the Native American Student and Community Center on the Portland State University campus . The abstract sculpture , made of wood , bronze , and stainless steel , depicts salmon in the Columbia River Gorge , and their journey from birth to spawning . Its pole is made from three trees that fell during the 1980 eruption of Mount St. Helens . Images of salmon eggs appear at the base . The middle of the pole shows an image of Pitt 's '' She Who Watches '' . MacKintosh 's depiction of two salmon mating , as well as an abstract image of a salmon , appear at the top of the pole . According to Portland State University , the work is inspired by totem poles , and serves as a metaphor of " regional symbolism "
