Dead Man's Lake is one of the few natural floating peat bogs found in Iowa.
The park's stone observation tower was built during the Great Depression by the Civilian Conservation Corps (CCC).
The summit elevation reaches approximately 1,450 feet above sea level, making it the second-highest point in Iowa.
The landscape was shaped by the Wisconsin glaciation, resulting in the distinct 'knob and kettle' topography.
The park provides habitat for the rare Hine's emerald dragonfly.
Pilot Knob State Park is a 700-acre glacial moraine located in north-central Iowa, featuring the second-highest point in the state. The park is home to Dead Man's Lake, a rare quaking bog that acts as a floating mat of vegetation. An observation tower constructed by the Civilian Conservation Corps in 1934 stands at the summit, offering views of the surrounding Winnebago County landscape. The terrain encompasses diverse ecosystems, including prairie remnants, oak savannas, and woodlands. Four miles of rugged hiking trails traverse the uneven, glacier-formed topography. Winter activities include snowmobiling and cross-country skiing, while the summer months focus on birdwatching and fishing. The park was established in 1923 and remains a significant site for geological study regarding the Des Moines Lobe of the Wisconsin glaciation.
