Danger - White Water
Slippery Rock Creek visitors entering McConnells Mill State Park should be aware of the natural hazards and steep terrain of the Slippery Rock Creek Gorge. This area contains smooth rocks that are often damp and slippery, and varying degrees of whitewater conditions, including deep pools, rapids, and swift currents.
Adults should be aware of these features and exercise caution to protect themselves and children from accidents. Numerous accidents here have resulted in injury and death.
