Huntington

Huntington's old nickname, "The Lime City," points to the limestone quarrying that shaped the town, and Indiana's limestone quarry belt generally produces calcite, pyrite, marcasite, sphalerite, and occasionally small geodes in the void spaces of the rock.[1][2] Huntington County's lakes and streams also concentrate glacial gravel worth a look. That's the honest picture for this location: the regional geology supports the specimen list, but no source names a specific, currently-open quarry or public site in Huntington itself. Treat this as a general-area stop tied to Indiana's limestone country rather than a pinned destination until a specific site is confirmed.

Huntington sits in northeast Indiana on the Little and Wabash Rivers, along US-24. No specific quarry, pit, or public access point could be confirmed for this location — general guidance is to look for active club-permitted quarry visits or public gravel operations in Huntington County rather than a single named spot.

Where a legal site is found, this is surface/void-collecting in broken limestone — no digging, just checking seams and cavities in quarry spoil for crystal-lined pockets. Quarry access in Indiana is typically limited to organized club field trips with prior arrangement; walk-up access to active quarries is uncommon and often prohibited for safety and liability reasons.[2]

Land status here is UNVERIFIED — confirm ownership and permission before visiting any specific site. Active limestone quarries are private industrial operations with real safety hazards (blasting, unstable walls, deep water in flooded pits); do not enter an active quarry without explicit permission, and treat "no trespassing" signage as absolute. If a public fossil/mineral collecting area exists in Huntington County, it was not identified in this research pass.
