Vaughn

Vaughn is a small ranching community on the Sun River in Cascade County, north of Great Falls. The database lists silicified wood here, and Montana's Missouri River drainage generally does carry scattered silicified wood as float, eroded out of Tertiary-age volcanic ash deposits upstream and redeposited in river and creek gravels across the region. But no source found ties a specific, documented collecting site to Vaughn itself — Vaughn's own written history (a ranching town founded by Robert Vaughn, who tried gold mining near Helena before settling here) has nothing to say about local rock collecting.[1] Treat this as a general area, not a confirmed pinned locality, and go in with modest expectations.

Vaughn sits on U.S. Route 89/287 in the Sun River Valley, about 15 miles northwest of Great Falls. No specific trailhead, pullout, or gravel bar is documented as a collecting spot.

General-area inference only: if silicified wood float exists here, it would most likely turn up in river or creek gravel bars along the Sun or Missouri River, the standard method for this material elsewhere in Montana — surface-walking gravel bars after high water, no digging required. Unconfirmed for this specific location.

Land status around Vaughn is UNVERIFIED. The area is predominantly private ranch and farmland (Vaughn's own history is agricultural, not public land), with scattered state and BLM parcels elsewhere in Cascade County. Confirm ownership and get permission before collecting anywhere off a public road right-of-way. No land manager or specific access point could be confirmed for this dossier.
