The Knowlton Outdoor Athletic Complex, which opened in the fall of 2013, includes the Charles D. Lindberg Stadium, the Ken Anderson Academic All-American Club and the Players' Plaza, Viking Patio and Overlook.
The Ericson Field playing surface was redone in the summer of 2012 and the Paul V. Olsen Track was installed in 2008.
The complex is named in honor of the late Ohio businessman and philanthropist Austin E. Knowlton.
