The "garden" of rock formations was created from a natural fault line upheaval millions of years ago. A gathering place and spiritual center for almost ten Native American tribes, the geological croppings in the park show ancient sedimentary beds tilted on edge or stacked vertically by the pressure of the mountain-creating forces that ultimately formed the Rocky Mountains and nearby Pikes Peak. Closer inspection of the rocks shows evidence of ancient glacier activity, forgotten seas and beaches, ancestral mountain ranges, dune fields, and eons of erosion. The morning we visited, many of the rocks seemed to glow orange and red in the new day's sun, especially Balanced Rock.
See below for some pictures from the driving loop in the park. Pictures 1 and 3 below from the Blux Pro app for iPhone5, the remainder were snapped with a Nikon D90 and my go-everywhere 18-105 lens.
