Grinnell's natatorium is part of the Charles Benson Bear '39 Recreation and Athletic Center that was completed in 2010. The natatorium reflects the latest technology and design, offering swimmers a magnificent place to compete, train, or pursue personal fitness goals. The flexibility of the facility is one of its greatest strengths. Two movable bulkheads can reshape the pool for different purposes. The pool and deck portion of the natatorium were named after former Grinnell College president Russell K. Osgood in October 2010. The natatorium is connected to Darby Gym and the fieldhouse via an underground link and features:
