Oregon is a Rockhounding Paradise: All the Best Public Sites Are Right Here

rockhounding oregon

Since before I knew there was a word for it I’ve been a rockhound. As a young child I would pick up pretty rocks anywhere I could and save them in small boxes labeled with various mineral names. In my twenties, I spent countless hours annoying friends and family at Oregon beaches and creeks. They wanted to party or hike. I just wanted to hunt for agates. Today at 40 I proudly have piles of various crystals and minerals residing in my garden and around my home (somewhat to the annoyance of my significant other).

People who love rockhounding have various reasons for doing it. As humans, I think we’re all naturally drawn to shiny objects to differing degrees. Some folks look at the monetary value of what they collect. Others are jewelers and craftspeople. Brainy-types get hooked on the molecular composition of minerals. Some of us are just hoarders of beautiful objects.

Whatever your reason for collecting rocks and minerals, Oregon is a mecca of a playground for you. From the coast to all three inland borders, here is your beginner’s guide to finding gorgeous rocks in our beautiful state.

Know Your Rocks!

There are three main types of geological rocks:

  • Igneous: Formed by magma deep in the earth. Volcanic activity pushes magma to the surface where it cools at varying rates, creating crystals (like Oregon Sunstone), volcanic glass (Obsidian), or Basalt (this plain, gray rock makes up much of the surface in our state, as well as our mountains and rocky outcroppings).
  • Sedimentary: Sediment is a naturally occurring material that is broken down by the processes of weathering and erosion. Volcanic ash from centuries-old eruptions in Oregon is one example. Over time, these layers of sediment become compressed and fused together creating substances such as sandstone (very commonly found at the Oregon coast), limestone, and coal.
  • Metamorphic: Here, the name says it all. These are rocks that underwent a fundamental change. They started life as either sedimentary or igneous, but their chemical structure was disrupted by things like high heat or extreme pressure. They became a different mineral altogether.

What Kinds of Things Do I Need to Bring on a Rockhounding Adventure in Oregon?

This completely depends on where you intend to go. For agate hunting on the Oregon coast, you may need nothing more than a bag or bucket for your finds. If you’re hunting for Carnelian in rivers and streams, water shoes or waterproof boots may be a good idea. On dry land in forests and high desert, you may want other implements such as:

  • A portable shovel
  • Rock pick
  • Rock hammer
  • A screened sieve or colander
  • Gloves
  • Safety glasses
  • Water (to clean off dirty finds)
  • A wire brush (for scrubbing)
  • Bucket
  • Good shoes
  • GPS unit
  • BLM map

The most important thing is knowing where you are allowed to dig and what places are off-limits. Public lands are generally okay for rockhounding, but different areas may have different rules for how much you’re allowed to collect in one day. Sometimes only surface collecting is allowed. Other spots allow digging, but holes must always be filled in to Leave No Trace for future hunters and hikers. Bottom line? Know before you go.

Enough Formalities…Show Me the Rockhounding Sites!

One thing to keep in mind is that cool rocks are EVERYWHERE. I’ve personally found awesome specimens of jasper and quartz just by pulling over at roadcuts to sift through the rubble, but it’s a known fact that certain areas of Oregon are better for finding specific types of beautiful rocks.

Garrett Romaine’s book Gem Trails of Oregon was an early rockhounding bible for me, and I highly recommend it to anyone wanting to start searching for their own minerals and gems in Oregon. Much of this information was compiled from there, as well as Mike Rhea’s awesome resource site.

The Ten Best Locations to Rockhound in Oregon


Professional rockhounds have their sites that we will never know about. One guy on a Facebook rockhounding group I follow regularly finds gorgeous amethyst crystals in the hills somewhere around Tillamook, but he’ll never give up the location. And I totally understand and respect this mentality. It just goes to illustrate how rocks can be found anywhere if you know where to look.

Don’t forget to read to the bottom of this article for an interactive map of all the rockhounding sites mentioned in this article.


1. The Owyhee Canyonlands

County: Malheur

This diverse and extraordinary corner of SE Oregon makes up an area nearly as large as Yellowstone. Flat desert spreads out into giant rocky crags and flowing streams, deep and mountainous. It’s truly a place to get lost in nature. Juniper Gulch and Succor Creek Canyon are two of my favorite rockhounding sites here.

  • Rocks to Find in the Owyhees: Picture jasper, thundereggs, quartz, agate, petrified wood, fossils.

2. Priday Agate Beds

County: Jefferson

Richardson’s Rock Ranch used to be my favorite spot to dig thundereggs, but unfortunately, they’ve closed to the public (although you can still visit the gift shop to purchase thundereggs dug by the owners). Alternatives in the area include the Polka Dot Agate Mine and a public dig site, Canyon Rim. The Priday Beds are well known in Central Oregon for producing some of the most stunning specimens of agatized and opalized thundereggs.

  • Rocks to Find at the Priday Agate Beds: Polka dot agate, plume agate, thunder eggs.

3. Glass Butte

County: Lake

Glass Butte is a volcano that formed about 4.9 million years ago. Here you can find many gorgeous types of obsidian, including rainbow, black, pumpkin, mahogany, gold sheen, and double flow.

4. The Nehalem River

County: Columbia

The Nehalem River is one of the best places to find beautiful carnelian agate, which ranges in color from yellow to orange and deep red. Search in public areas along and in the river near Timber Road, Clear Creek Road, and the Banks-Vernonia State Trail.

  • Rocks to Find on the Nehalem River: Carnelian agate, plume agate, jasper.

5. Lakeview Area

County: Lake

Lakeview is the county seat of Lake County, Oregon, and rockhounding opportunities abound here.

Flook Lake in the Hart Mountain National Wildlife Refuge is actually an ancient dry seabed and you won’t find any water here. Instead, sagebrush and wildflowers make up this alien-looking place. Nearby, dig Oregon’s State Gem, the Sunstone at the BLM Public collection area. Other popular rockhounding sites in Lake County include DeGarmo Canyon, the Warner Mountains, and (the very hospitable-sounding) Arsenic Canyon.

  • Rocks to Find in the Lakeview Area: Oregon Sunstone, agate, fire opal, obsidian, jasper.

6. Opal Butte

County: Morrow

Making up part of the Blue Mountain Range in NE Oregon, Opal Butte has been known to geology enthusiasts since the late 19th century. From the information we’ve been able to gather, the area is primarily private timber property but the road up to the peak is public. Always obey “No Trespassing” signs.

  • Rocks to Find at Opal Butte: Varying types of opal including fire, jelly, hyalite, rainbow, blue, and dendritic. Oregon jade, agatized petrified wood.

7. Mt. Pisgah

County: Lane

Mt. Pisgah is a very popular hiking location in Eugene with beautiful trails and an arboretum. I’ve been able to take long walks here and pick up cool specimens while just soaking up nature. Look for interesting quartzes and jaspers near river and stream banks.

  • Rocks to Find at Mt. Pisgah: Agate, calcite, heulandite, jasper, malachite, mesolite, quartz crystals.

8. Maury Mountains

County: Crook

Located in the beautiful Ochoco Mountains of Central Oregon is the Maury Mountain Agate Bed. Although very little material is available for collection on the ground surface, nice pieces of moss agate can still be found by rockhounds willing to take the time and effort to dig.

Rocks to Find at Maury Mountain Agate Beds: Moss agate.

9. White Rock Springs and White Fir Springs

County: Crook

This is another area near the Ochocos well worth a mention for rockhounding (as is most of Crook County in general). Nearby is Mill Creek Wilderness where digging is prohibited, so be aware. Both sites are public for small thundereggs and nodules.

Rocks to Find at White Rock and White Fir Springs: Thundereggs, jasper-filled thundereggs, agate, chalcedony, opal.

10. The Oregon Coast

Counties: Clatsop, Tillamook, Lincoln, Coos

While some areas are definitely more productive than others, the entirety of Oregon’s coastline is ripe for picking agates and fossils. Look for exposed gravel beds at low tide, and even further up the beach from the water. Agates are lighter than some of the other sandstones and wash up in the rolling waves. Our favorite spots include Moolack Beach, Oceanside, Nelscott Beach, Yachats, and Gold Beach, but I’ve found agates on most beaches I’ve visited in Oregon.

Rocks to Find on Oregon Beaches: Agate, chalcedony, jasper, fossilized seashells.

The sites mentioned above are just the tip of the iceberg for sites to rockhound in the State of Oregon. The map below shows many more popular locations:
