The Geology of Mt. Mansfield State Forest

The pamphlet guides visitors through the geology of the Mount Mansfield area in four parts: rock descriptions, structural geology, glacial history, and site-specific observations. It explains that the dominant rock is a mica‑albite‑quartz schist produced by metamorphism of ancient marine sediments under heat and pressure, which created foliation and later folding. The account describes subsequent uplift and erosion that exposed the schists, summarizes evidence used to assign a Cambro‑Ordovician age of roughly 380–500 million years, and notes regional correlations to formations sometimes called Pinney Hollow or Camels Hump, concluding with accessible field examples for observing the described features.
