Silers Bald consists of Thunderhead sandstone, a small pile of which crowns the summit. This sandstone, part of the Ocoee Supergroup, was formed from ocean sediments nearly a billion years ago. The mountain, like most of the Smokies, was formed some 200 million years ago when the North American and African plates collided during the Appalachian orogeny, pushing the rock upward.
