About this location
Chillicothe is the Ross County seat in south-central Ohio, and it's the anchor name for a real, documented pyrite locality — but the collecting itself happens on private property northwest of town, not at Chillicothe proper. Collectors (notably Jay and John Medici, per mindat records) have documented distinctive pyrite crystal clusters dug from blue clay and shale exposures in the area between Deerfield, Frankfort, and Chillicothe. The crystal forms are unusual enough that some specimens were initially mistaken for marcasite before analysis confirmed pyrite, with shapes suggesting they formed in ancient marine burrows and other voids in the rock. This is a real, named locality worth documenting, but not one with a public access point — every source describes it as private land.
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.
Found Here
- Pyrite — documented via mindat records: crystal clusters found in blue clay/shale exposures in the region between Deerfield, Frankfort, and Chillicothe, Ross County. Some specimens show unusual crystal habits (initially mistaken for marcasite) attributed to formation in marine burrow voids.
Difficulty
Getting there
Chillicothe is the Ross County seat in south-central Ohio. The specific pyrite-bearing clay/shale exposures are described only in general terms as being in the region toward Deerfield and Frankfort, northwest of Chillicothe — no source in this research pins down an exact, publicly-accessible outcrop.
Collecting here
Not applicable at a public level — see access notes. Where documented, collecting has meant working exposed blue clay and shale for crystal clusters, on private ground.
Know before you go
Every source found describes the specific pyrite localities near Chillicothe as private property. There's no confirmed public access point. If you're a Ross County landowner or know one with blue-shale exposures, that's the realistic path here — not a public dig site.
