Whitewater Preserve 6 th Grade Class Field Trip 2012

Meandering River This picture shows the path of the winding river N: 33º W:116º39.529

Evidence that Rivers Change Over Time The dirt in the middle of the river has been piled up and the river has been rerouted because of deposition. N:33º W:116º

A Place Where Erosion is Occurring Right Now This shows where water has eroded the side of the hill and left a gap or a ditch. N:33º W:116º39.559

Deposition of Sediments This is an example of sediment layers that were deposited on the mountain. N:33º W:116º39.438

Evidence of Big Flood Events in the Past This rock was carried all the way down the river, almost to the shore by a big flood. Only large amounts of water have the capability to do this. N:33º W:116º39.563

Another Interesting Geological Process This shows that mud washed over to shore and dried into clay in a thin layer on top of the dry sand. N:33º W:116º39.555
