The Geology of Darling State Park

A field-oriented guide to the geology of the state park centered on Burke Mountain outlines basic geologic concepts and geologic time, then describes local rock types and their history. It contrasts the prominent biotite granite outcrops with metamorphic layers of the Gile Mountain Formation, interprets their origins and intrusive relationships, and places them within a Devonian-era sequence roughly 300 million years old. Illustrated with maps, photographs, and microscopic images, the pamphlet offers route-specific observations for visitors, discusses glacial and structural features, and notes the area's natural history with references to future treatments of flora and fauna.
