Purdue & Canyon Creeks

Purdue Creek is a small stream in Latah County, Idaho, near Deary and Bovill, and it carries real weight in the gem world: Idaho's star garnet placers are documented here, and Idaho is one of only two places on Earth (along with a district in India) producing star garnets in significant quantity. That's a genuinely notable claim. But star garnet is functionally synonymous with one specific, developed public program in Idaho — the Emerald Creek Garnet Area, a U.S. Forest Service permit dig site near St. Maries, described by the Forest Service as the only place in the world where the public can legally dig for star garnets. Purdue Creek is a different drainage, roughly 60 miles north, and its garnet placers appear to fall under the Idaho Garnet Abrasive Placer holdings — a commercial mining claim complex spanning Latah, Benewah, and Shoshone counties. That points toward active private claim ground, not open public digging.

Purdue Creek is in Latah County, Idaho, near Deary and Bovill. "Canyon Creek" is presumed to be a companion or tributary drainage in the same immediate area, based on the paired DB entry name — UNVERIFIED, no independent source specifically confirmed a Canyon Creek by that name adjacent to Purdue Creek.

Star garnet placer material is typically worked by shoveling and screening stream gravel — the same basic method used at the developed Emerald Creek site. No source, however, describes an established public collecting method or access point at Purdue Creek itself.

Purdue Creek's garnet placers appear to fall within the Idaho Garnet Abrasive Placer claim holdings, a commercial mining operation with claims across Latah, Benewah, and Shoshone counties — treat this as likely active private claim ground rather than open public land. The Idaho Department of Lands notes that collecting on Idaho state trust land generally requires an access permit; if any part of this drainage crosses state trust sections, that rule would apply too. If you want a confirmed, legal public star-garnet dig, the Emerald Creek Garnet Area near St. Maries (U.S. Forest Service, $10/day permit, 5-lb daily limit) is the real, developed alternative: https://www.idl.idaho.gov/mining-minerals/dredge-placer-mining/recreational-mining/.
