The presence of limestone and ocean marine fossils at the top of these mountains is one of the key pieces of evidence cited that advanced the idea of plate tectonics (large chunks of the Earth's surface moving over molten rock in the Earth's core) when it was first proposed as a theory in 1915.

Limestone is a very common sedimentary rock consisting of more than 50% calcium carbonate. Although it occurs in many different forms, its origins can be traced back to either chemical or biochemical processes that occurred in the geological past, often tens to hundreds of millions of years ago. The best example is the Redwall Limestone, which commonly contains fossil brachiopods (a type of clam), corals, bryozoans (lace corals), crinoids (sea-lilies), bivalves (other types of clams), gastropods (marine snails), trilobites, cephalopods, and even fish teeth. 3 These marine fossils are found haphazardly preserved in this limestone bed.
