Shaking Rock derived its name from a 27-ton boulder that was so perfectly balanced atop a granite outcrop that it could be moved by the pressure of a hand . Over time , the elements have disturbed this balance to a degree that the boulder can no longer be moved . Reportedly , the " shaking rock " was knocked to the earth by the 1886 Charleston earthquake . Other huge natural granite outcroppings in unusual shapes are scattered throughout while a picnic area active beaver pond , and several nature trails with identified trees enhance the park
