Unconformity, where rocks that are 1.7 billion years old are found layered next to rocks that are about 520 million years old. The rocks on the right side of the historical site are 1.7 billion-year-old Precambrian granite and schist. They formed deep within the earth in the core of an ancient mountain range. During hundreds of millions of years this old mountain range eroded away, leaving the rocks exposed about 500 million years ago. The rocks were then buried by sand when the area was covered by a shallow sea. The sand cemented together to form the sandstone seen to the left of the historical site. The buried erosion surface is the Great Unconformity, which represents about 1.2 billion years of missing his­tory. The earth is about 4.5 billion years old, so this surface represents more than one-fourth of the earth’s history. Under foot and paw: Old dirt road with rocky areas.
