About this location
Coffee Creek sits in the Klamath Mountains of Trinity County, on the edge of the Trinity Alps Wilderness northwest of Trinity Center. The creek and the surrounding drainage gave their name to the Coffee Creek (Coffee) Mining District, a cluster of small historic gold prospects — the Nonpareil, Chapman, Golden Jubilee, Forget-Me-Not, and several others — worked from the late 1800s into the early 1900s [1][2]. The district's ultramafic and serpentine bedrock, typical of the Klamath Mountains ophiolite belt, is what produced the anthophyllite and serpentine this listing flags, alongside a longer documented mineral list that includes chromite, chrysotile, native gold, hematite, pyrite, and uvarovite [1]. Most of the named historic mines here are closed or inactive today, with no indication any are open to visitors [2][3]. This is a district worth knowing for its geology and mining history more than as a turnkey collecting stop — treat it as national forest ground where you check current claim status before you dig, not a mapped public dig site.
Always seek permission where required, follow local laws, and practice Leave No Trace. Locations and details are community-submitted and may be inaccurate. Not sure what's legal here? Read our full guide to rockhounding laws by land type.
Found Here
- Anthophyllite — an amphibole mineral documented in the Coffee Creek district's serpentine/ultramafic rock; no site-specific abundance or quality data found [1].
- Serpentine — the host rock of the district, common throughout this stretch of the Klamath Mountains ophiolite belt [1].
- Mindat's district mineral list also includes calcite, chalcopyrite, chromite, chrysotile, native gold, hematite, pyrite, quartz, siderite, and uvarovite [1] — UNVERIFIED which, if any, are surface-collectible outside the old mine workings themselves.
Difficulty
Getting there
Coffee Creek is reached via Coffee Creek Road off State Route 3, roughly 40 miles northwest of Trinity Center in the Klamath Mountains [2]. The named historic mines (Nonpareil, Chapman, Golden Jubilee) sit on National Forest System land in this drainage [1][2] — exact mine locations are UNVERIFIED beyond district-level mapping, and a high-clearance vehicle should be assumed for any forest-road approach.
Collecting here
General-area inference: surface/float collecting of serpentine and associated ultramafic minerals along the drainage and road cuts is the realistic method here, not shaft or adit access — the named historic mines (Forget-Me-Not, Morrison Gulch) are documented as closed with no reopening plans [3]. Hand tools only. Best season is summer through early fall; this is high-elevation Trinity Alps country and snow closes access much of the year (UNVERIFIED exact elevation/season for this specific drainage).
Know before you go
This is Shasta-Trinity National Forest ground in the Trinity Alps area. The Forest Service permits personal-use rockhounding on National Forest System land only where mineral rights aren't privately held, collecting isn't specifically prohibited, and only small hand tools are used — see the Forest Service's national rockhounding guide [4]. Because this drainage carries a real, named mining district with historic claims, confirm with the Shasta-Trinity National Forest ranger district whether any ground here is currently claimed before you collect — claimed ground is off-limits without the claimant's permission. Land status for this specific listing is otherwise UNVERIFIED.
