Above: This photo, taken from the top of the Ringing Rocks, shows a granite outcropping that is typical of the Boulder Batholith. The granite is much lighter-colored than the gabbro of the Ringing Rocks shown below. Below: A group of students relax on top of the Ringing Rocks. Notice that the rocks are less rounded (more angular) than those in the top photo. |
