Description
The most likely origin of the Split Rock and the Sphinx Rock was the top of Grandfather Mountain. Thousands, maybe millions of years ago, the boulders broke from the upper outcrops on Grandfather Mountain and fell (rolled?) to their current resting places. Before arriving at their current locations the rocks were most likely underwater. The type of rock (metaconglomerate) also means they were created millions of years ago as a stream bed in a previous mountain formation that likely pre-dated the current Appalachians. Unlike the Appalachian and Blue Ridge Mountains, the rocks are thought to be over 650 million years old!~ Information from www.geocaching.com
