Worland area (Bighorn Basin)

Worland sits on the Big Horn River in the middle of the Bighorn Basin, and while the town itself isn't a mineral locality, it functions as a natural home base for the agate and chalcedony hunting the basin is known for. Volcanic-origin agates and chalcedony turn up in stream gravels across the western Bighorn Basin — Big Horn, Hot Springs, Park, and Washakie counties — and limb-cast agates have been reported directly along the Big Horn River. This is a "region," not a single mapped site: expect to work river gravel bars and BLM parcels rather than follow directions to one spot. Honest framing: Worland is a reasonable jumping-off point for Bighorn Basin agate hunting, not itself a destination with a named collecting site.

Worland is on US-16/20 in Washakie County, Wyoming. Bighorn Basin gravel bars and BLM land accessible from Worland extend along the Big Horn River and its tributaries; no single trailhead applies.

General surface/streambed picking in river gravel bars — sturdy boots, a rake or small shovel for turning gravel, and patience. Best worked after high water (spring runoff) has reshuffled gravel bars. General-area inference; not verified against a specific Worland-area site.

Recreational rock collecting for personal, non-commercial use is generally allowed on Wyoming BLM land and in the state's National Forests (Bighorn, Bridger-Teton, Medicine Bow-Routt, Shoshone), per BLM's general Wyoming guidance. Confirm the specific parcel you're on is BLM/public and not private ranchland — the Bighorn Basin is a checkerboard of public and private land, and river frontage is often privately owned.
