The Power of Water

Here at stop number five, take a pause and look around. You may notice a small stream flowing in front of you, depending on the season. Many creeks flow down to the river, ranging from small, dry rivulets to broad streams that need a bridge to cross. This one in particular is intriguing. Look at it. What makes it so special?

What did you see? Maybe the strange pile of rocks near the confluence* of the stream and the Cathance River? Theis pile of orange-colored rocks is a great example of the power of water and how streams can erode and move large rocks over thousands of years. The rocks in this pile look like they came from similar larger rocks upstream. The distinctive orange-red color comes from iron-rich minerals present in the rock. Also important to note, only the larger pebbles and rocks remain, since smaller particles no doubt continued their journey down the river in fast-moving water.

You may see the power of flowing water in other places on the preserve, especially in and around the river. Keep an eye out for places where the river eroded large rocks to create an easier path!
