To the left is printed matter reading, "Summer Lake was formed by tectonic forces that pushed and twisted this landscape into ridges and valleys over the past ten million years. Winter Ridge, rising to the west of the lake, is Summer Lake's "fault scarp." Millions of years ago, the bedrock of the ridge and the bedrock underlying the lake were pushed together (this is struck through and "pulled apart is written above in black Sharpie). The lakebed sank, and the bedrock split along a north-south fault line, and Winter Ridge rose, forming a steep slope - a scarp - between the two faults." To the right is a diagram of the area with arrows showing the movement of the fault. The arrows clearly show that the two sides pulled in opposite directions, and the center dropped down.")
