Recreation

Parks

There are two Pennsylvania state parks in Butler County. Before the glacier dam, Slippery Rock and Muddy creeks flowed north while extinct McConnells Run flowed south. The glacier dammed Lake Prouty on the edge of the drainage divide. Eventually Lake Pouty spilled over and rushed to the south, carving Slippery Rock Creek Gorge. Lakes Watts and Edmund drained into the gorge, digging it deeper and making Slippery Rock and Muddy creeks flow south. Areas of the 400 ft deep Slippery Rock Gorge may be seen at nearby McConnells Mill State Park. The glacier created a landscape of rolling hills topped with hardwood trees and swamps in the valley bottoms. Moraines containing gravel, sand and clay were draped upon the landscape and silt was left on the extinct lake bottoms.
