 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.While Silers Bald is hardly mentioned in Cherokee lore, a petroglyph was discovered near
the summit in 1917.
