The ridge along upper distance is composed of the Lower to Middle Cambrian Carrara Formation, roughly 535 to 515 million years old; the Carrara yields many species of trilobites and algae nodules, in addition to world-class suites of ichnofossils--tracks and trails of invertebrate animals that crawled across the muddy sea bottom over a half a billion years ago. |
