What Are Oregon Geodes?

Geodes are cool rocks that form in volcanic or sedimentary environments. Their formation begins when minerals start to crystallize inside a hollow space. Over time, these crystals continue to grow until they fill the cavity completely, creating a solid rock with a crystal-lined interior. Oregon’s unique geology can amply support this process.

Geodes can be found in a variety of colors and patterns, depending on the type of minerals that formed them. They’re often cut open and polished to reveal their inner beauty. Indeed, geodes are a fascinating geological phenomenon and a popular item for collectors and enthusiasts alike.

If you’re curious to know how the outside of a geode rock looks like, we created a simple guide to quench your curiosity.

The Types Of Geodes Found In Oregon

Oregon is home to several varieties of this natural wonder, and how much a geode is worth depends on it. Below, we have listed some of the types of geodes you are likely to come across in our region.

  • Agate geodes
  • Black Agate geodes
  • Chalcedony geodes
How We Found The Best Geode Locations in Oregon
When it comes to choosing the best options for finding Oregon geodes there are plenty of things we consider. Many of the best locations are closely guarded secrets which can make it really difficult for more casual geode hunters to find success. The key factors in our recommendations are:

  • The deep experience and understanding of our team about the area
  • Recommendations from local groups and clubs
  • How easy it is to get the a particular location
  • Safety and potential hazards when collecting
  • Weighing private and public locations

With these factors in mind we’ve been able to put together a fantastic list that just about anyone can use!

The Best Places To Find Geodes in Oregon

You may be familiar with the best places to find gems in Oregon. Unfortunately, not all of them contain geodes. The locations we’re sharing with you below may not be as well-known, but they are definitely the best places to visit if you want to find geodes here.

Always Confirm Access and Collection Rules!

Before heading out to any of the locations on our list you need to confirm access requirements and collection rules for both public and private locations.

These requirements are subject to change without notice and may differ from what we state below.

Always get updated information directly from the source ahead of time to ensure responsible rockhounding.

Steens Mountain

Part of the Great Basin, Steens Mountain is located in the southeastern part of our state. It’s a big old mountain rising to over 9,000 feet. Its terrain is rugged and wild, with steep cliffs and canyons. What’s fascinating about its geology is that it’s made up of volcanic rocks that were formed millions of years ago. You can see layers of ash and lava all over the place.

As you might’ve already guessed, getting here is a bit of a trek. You’ll have to drive for miles on dirt roads (no cell phone service out here!), but once you get here, you’ll feel like you’re on top of the world— and atop a pile of geodes just waiting to be discovered.

But before you plan your trip, make sure to check the latest collecting guidelines of Oregon.

Where we found geodes at Steens Mountain

Lucky for you, there are a number of specific spots at Steens Mountain where you can find geodes! Particularly, these are the west side of the mountain via route 78 of Burns and all the regional land surfaces, draws, and washes on the east side of the mountain via the Alvord Ranch, Andrews, and Fields.

The tools every geode hunter will need

When you're out looking for geodes having the right tools for the job is very important. You don't need a lot for most trips but there are a handful that are critical and will make your life a lot easier.

We get asked a lot about the equipment we use. Over the years we've found a handful of tools that we recommend to both new and experienced geode hunters which we outline in great detail in our complete rockhounding tools and kit guide. These are quality options that also happen to be relatively inexpensive.

Below are the basic tools that make your life so much easier and save you a ton of time. Check out the full guide to see everything we recommend bringing. One quick note, as an Amazon Associate I earn from qualifying purchases but we try very hard to only recommend gear we would use ourselves and often recommend brands you can't find on Amazon.

At a minimum you should have:

1 - Sturdy rock hammer: The Estwing Rock Pick is our standard

2 - Rugged chisels: Try Kendo' 3-piece Chisel Set

3 - Compact shovel: The Koleiya 28-inch shovel works well

4 - Rock screen pan: The Wazakura Soil Sieve Set fits the bill

5 - Eye protection: DeWalt Safety Glasses are cheap and comfortable

6 - Head protection: Malta's Safety Helmet has been our go-to

7 - Jewelers lens with at least 20x magnification: Jarlink's Jewelers Loop is perfect

The geode-finding books that we use most

There are also a few books that have been extremely helpful in the search for gems. These books have great recommendations and tips:

National Audubon Society Field Guide to Rocks and Minerals: North America

There are some steep canyons along it, too, that make for some pretty epic views. The area is rich in gold, which is why there are still some active mines in our region.

To go here, there are a few highways that run through the area. Overall, we recommend Powder River if you’re after some amazing geode hunting adventure.
