The JUNIATA JOURNAL of GEOLOGY, 1, 1-7 (2014) Original Article Identifying the Distinct Rock Types in the Streambed of Muddy Run Kristin N. Kopera Pennsylvania has many secondary and bedrock streams, and one such stream is Muddy Run. Muddy Run is located primarily in the Hamilton Formation, but also touches the Onondaga and Ridgeley Formations in Huntingdon County, Pennsylvania. This paper identifies the rock types that are currently in Muddy Run, and matches them to the local geologic formations. Instead of primarily finding Hamilton Group in the stream, the majority of the samples taken from Muddy Run were from the Tuscarora and Ridgeley Formations. This suggests that Muddy Run had, at one time, come in contact with the Tuscarora formation. This data could also suggest that Muddy Run once belonged to a larger stream that transported the Tuscarora sandstones and deposited them in Muddy Run’s current location.

[email protected] INTRODUCTION Huntingdon County, Pennsylvania, is one such example. Bedrock streams, instead of just Rivers and streams are the main transporters of flowing over the ground, cut down into the local sediment and rock and they are known for their bedrock (Seidl & Dietrich 1993). This following powerful erosional capabilities. Sediment and paper will answer two questions concerning rock travel down gradient from location to Muddy Run. Firstly, throughout its geologic location until they come to rest in a delta history, from what locations has Muddy Run .Alternatively, the sediment could also be been eroding and transporting rock? In addition, deposited when the velocity of the water has where did the rocks in Muddy Run once belong become too slow to move the debris any farther.
