Griswold Stadium is an American football and soccer stadium which serves as the home of the Lewis & Clark Pioneers football and soccer teams. It is located in Portland, Oregon, featuring an AstroTurf field and a seating capacity of 3,500. It has hosted track and field events as well. The land that the stadium sits on was forested before it was built. In 1952, Graham Griswold donated US$25,000 and lumber towards the erection of a new football stadium, complete with grandstands.
