The SummerStage is an outdoor stage in a natural amphitheater that hosts shows including plays, musicals, and dance as well as summer theater camps.

[4] Madison-area architect Mark Alan Kraft created the final blueprint for the rehabilitation from private residence into nature center.

At the top of Lapham Peak is a wooden observation tower that is 45 feet (14 m) high and offers a dynamic view of southeastern Wisconsin and the northern edge of Illinois.

The Waukesha County Historical Society named the peak in memory of Increase A. Lapham to honor his efforts in scientific study and his founding of the United States Weather Bureau.

The peak's 45-foot (14 m) tower was erected a year later by a crew from the WPA (Works Project Administration) who also constructed trails, picnic grounds and benches.
