Geology at Chimney Rock Park NC
Geology

It took more than half a billion years to make Chimney Rock Park! The process began during the Earth's distant geologic past, when a portion of its molten interior welled up, cooled and solidified into a huge mass of granite deep below the surface. Jump ahead billions of years, after high temperatures and extreme pressure changed the mass from granite to Henderson Gneiss (pronounced "nice"), the rock that forms our magnificent namesake, the 535-million-year-old Chimney and surrounding cliffs.
