The Journey of Slip Run

Slip Run starts high up on a mountain in Davidson Township. It flows towards the east-southeast for a short distance. Then, it turns to flow south-southeast and enters a valley. After flowing for about a mile (1.6 kilometers), the stream meets West Branch Fishing Creek. This meeting point is not far from Fishing Creek Road.

Slip Run joins West Branch Fishing Creek about 10.26 miles (16.51 kilometers) before West Branch Fishing Creek reaches its own end.

Land and Rocks Around Slip Run

The land where Slip Run meets West Branch Fishing Creek is about 1,932 feet (589 meters) above sea level. However, where Slip Run begins, it's much higher. The source of the stream is between 2,320 and 2,340 feet (707 and 713 meters) above sea level. Slip Run is located on the northern side of North Mountain.

The rocks and land around Slip Run have been shaped by glaciation. This means that huge sheets of ice, called glaciers, once moved across the area. The edge of the last big glacier, called the Wisconsinan Terminus, crosses the area that drains into Slip Run. You can see many curved ridges of till (rock and dirt left by glaciers) near Slip Run. Also, large, rounded rocks called conglomerate erratics are found west of the stream's valley. These rocks were carried there by glaciers.

At the mouth of Slip Run, the ground is made of alluvium and Boulder Colluvium. Alluvium is soil deposited by flowing water. Boulder Colluvium is a mix of loose rock and soil that has fallen down hills. It has many large boulders made of sandstone, conglomerate, and quartz. Further upstream, the ground is made of bedrock (solid rock) like sandstone and shale. Boulder Colluvium is also found on a nearby high area. A large patch of Wisconsinan Till Moraine is along the upper parts of the stream. Beyond that, there is Wisconsinan Till, which is another type of glacial deposit.

Wildlife and the Area Around Slip Run

The entire area that drains water into Slip Run is called its watershed. This watershed covers about 0.53 square miles (1.37 square kilometers). Slip Run is completely within the United States Geological Survey map area called Sonestown. Most of the stream's length is in the western part of Pennsylvania State Game Lands Number 13. This is a special area for wildlife. However, the very beginning of the stream is not inside these game lands.

Wild trout fish are born and grow naturally in Slip Run. They live in the stream from its very beginning all the way to where it joins West Branch Fishing Creek.
