Second Annual Report on the Geological Survey of the State of Ohio (Classic Reprint)

Uncover Ohio’s hidden mining wealth and the promise of its minerals shaping the state’s future.

This edition presents the Geological Survey’s early findings and the scope of work across many counties. It explains how coal, slate, and limestone sit in three linked rock groups and how the survey maps their boundaries and connections to transport and industry. The text also highlights the potential value of limestone, marble, and other rocks beyond coal and iron, and shows how river and canal improvements could unlock new markets for mineral wealth.

• Learn how the survey divides Ohio’s geology into coal, slate, and limestone formations and how they relate to the state’s geography.
• See why coal is abundant and promising for canals, railways, and regional markets, with notes on beds near key counties.
• Discover mentions of limestone, marl, peat, and other useful minerals opening new possibilities for agriculture and construction.
• Understand the practical goals of surveying counties not known for mineral riches to show broader economic value.
