Fort Bridger

Fort Bridger is a small unincorporated community in Uinta County, Wyoming, built around the historic 1840s trading post and military outpost of the same name, now a Wyoming State Historic Site. The town itself isn't a collecting site — but the surrounding country is part of the Bridger Formation, a well-documented Eocene badlands unit known regionally for petrified wood and agate. Treat the specimens listed here as general-area geology, not a pinpointed dig spot; we could not confirm a location any closer to Fort Bridger than "the Bridger Formation," which covers a large area of southwestern Wyoming.

Fort Bridger sits in eastern Uinta County on I-80/US-30, about 33 miles east of Evanston. The historic fort itself is a state historic site with fee entry to the museum grounds; the surrounding Bridger Formation badlands extend across the broader region. UNVERIFIED: no specific collecting pullout identified.

General-area inference only: surface and float collecting in badlands exposures of the Bridger Formation is typical for this kind of Eocene lakebed and floodplain unit. Not confirmed for any specific site near the town of Fort Bridger.

The historic fort grounds are a Wyoming State Historic Site — no collecting there. Land status around the wider Bridger Formation is a mix of BLM and private ranch land; Wyoming has roughly 18 million acres of BLM land open to personal-use recreational collecting, but you'd need to identify a specific BLM parcel near Fort Bridger and confirm it isn't private before digging. UNVERIFIED beyond that general framework.
