Pilot Knob State Park
Pilot Knob State Park delivers Iowa’s most unique geological landscape – knob and kettle terrain left behind by retreating glaciers 15,000 years ago. From the historic CCC observation tower on Iowa’s highest point (1,450+ feet), you’ll survey a primordial landscape of conical hills and bowl-shaped depressions. Below lies Deadman’s Lake, Iowa’s only floating sphagnum bog – home to carnivorous sundew plants found nowhere else in the state.
What Makes Pilot Knob Unique
CCC Observation Tower
A 34-foot tower built from glacial boulders, on the National Register of Historic Places. Panoramic views from 1,450+ feet elevation.
Glacial Terrain
“Knob and kettle” landscape – conical hills (kames) and bowl-shaped depressions (kettles) formed 15,000 years ago.
Deadman’s Lake
Iowa’s only floating sphagnum bog. Home to carnivorous sundew plants and rare pond lilies found nowhere else in Iowa.
Pilot Knob Lake
15-acre fishing lake for bass, catfish, and bluegill. Electric motors only. Popular for ice fishing in winter.
Observation Tower
The CCC-built observation tower is the park’s centerpiece – a 34-foot structure built from glacial boulders (igneous and metamorphic rocks carried from Minnesota and Canada by glaciers). Listed on the National Register of Historic Places, the tower offers sweeping views of Iowa’s highest terrain.

Deadman’s Lake – The Floating Bog
Deadman’s Lake isn’t a typical lake – it’s a 4-acre floating sphagnum bog, the only one of its kind in Iowa. The bog mat floats on water, creating unique acidic conditions that support:
- 🪴 Carnivorous Sundew Plants: These insect-eating plants thrive in the bog’s nutrient-poor conditions
- 🪷 Rare Pond Lilies: Three species, one found nowhere else in Iowa
- 🌿 Sphagnum Moss: The bog’s floating mat is composed of this unique moss
Viewing: The Deadman’s Trail circles the bog with interpretive signs. Do not step on the floating mat – it’s fragile and potentially dangerous.
