Circle Creek Overlook

Many of the granitic rocks in the Preserve form dome-like features. Igneous plutons that formed deep underground were later fractured by the release of pressure caused by erosion of overlying material through time. As the rocks became exposed near the surface, cracks (called joints) became passages where groundwater could seep into the rock causing the rocks to start to weather away. Today the landscape reflects the cumulative expression of the granite's exposure to weathering and erosional processes.
