Historical & Ecological Origin

Bald Mountain is an uplifted block of sedimentary rock, primarily composed of limestone and shale, formed during the Mesozoic Era. Its treeless summit is a result of high elevation and harsh alpine conditions, limiting tree growth. The mountain has been a focal point for recreation since the development of Sun Valley in the 1930s.
