At the MaST Center, we have a wonderful marine science program. We have a fine aquarium too. Every June, we release our giant pacific octopus back to the wilds of Puget Sound. They are an amazing animal to study and to interact with. Its truly a remarkable marine creature. On June 11, 2016...Salish went back to her home waters of Washington State. The Marine Science & Technology Center (MaST) is part of Highline College in Des Moines, WA.
