The Trinity River is in north-western California, United States, and the Klamath River’s main tributary.

It is a 1hr 52-minute drive from Eureka, CA.

On the trinity river, you can find rocks and minerals such as diamonds and platinum nuggets.

As you get closer to willow creek, you’ll definitely come across some pretty precious jade rocks.

The Trinity River is also known for gold panning.

The gold is not only found in the gravels of the stream channels, but also in ancient terrace and bench deposits next to the channels.

Hydraulic mining was commonly used to mine the terrace and bench deposits.

The gold in the trinity river is almost always obtained in its natural state in quartz veins, generally with pyrite and minor concentrations of other sulfides.

Veins may be found in all Jurassic and older metamorphic rocks.

Granitic rocks contain a few lode gold occurrences.

There are a few fundamental principles to observe before you start panning for gold on the Trinity River.

Prospecting and claiming on private land is not permitted.

To hunt for gold on private land, you must first obtain the landowner’s consent.

Check the region for a copy of a location notice to see if there is another earlier claim.

You may also gather information by interviewing local residents or looking up mining records in the county.

Prospecting and mining claims are normally allowed on federal property overseen by the Forest Service and the Bureau of Land Management.
