Bowling Green Area — Portage (Stoneco) Quarry, Wood County
About this location
The DB coordinates for "Bowling Green" actually land on Portage, a small Wood County community about 9 miles southeast of Bowling Green proper — home to the Stoneco Portage Quarry, an active dolomite building-stone operation in the Lockport and Greenfield dolomite formations. This is the real productive site behind the search demand: Wood County's cluster of limestone/dolomite quarries (Portage, Lime City, and others) is one of Ohio's best-known localities for celestite, matching the DB's specimen list of barite, calcite, celestite, fluorite, and pyrite. Celestine crystal groups up to 7.5 cm have been documented from the Portage quarry specifically. This is an active commercial quarry, not a public rockhounding site — access requires company permission or an organized club dig.
Always seek permission where required, follow local laws, and practice Leave No Trace. Locations and details are community-submitted and may be inaccurate. Not sure what's legal here? Read our full guide to rockhounding laws by land type.

Difficulty
Getting there
The Stoneco Portage Quarry is in Portage, Liberty Township, Wood County, Ohio, about 9 miles southeast of Bowling Green. This is a company-operated site with no public entrance.
Collecting here
UNVERIFIED for public/individual access. If arranged, expect standard active-quarry conditions — hard hat and safety gear, hand tools for breaking dolomite to expose celestite/fluorite pockets, supervision by quarry staff.
Know before you go
This is an active commercial dolomite quarry operated under the Stoneco name. No source in this research confirmed a walk-in public access policy — contact the operator directly, or look for organized mineral-club digs (Wood County's celestite quarries have periodically hosted club field trips historically, though current-year scheduling was not verified). Standard active-quarry hazards apply.
