What Are Washington Geodes?

Geodes are naturally occurring rock formations that have a hollow interior lined with crystals. They’re formed over millions of years when mineral-rich groundwater seeps into cavities in sedimentary and volcanic rocks. As the water evaporates, it leaves behind minerals that slowly build up and form crystal layers. With Washington’s unique geology, the formation of geodes is pretty easy!

To identify this natural wonder, it would help to know what the outside of a geode looks like, and we’ve got you covered on this, too.

With their unique appearance and mesmerizing beauty, geodes are sought after by collectors and are used by many for their decorative purposes. Who would not be amazed by geodes?

The Types Of Geodes Found In Washington

Our state is lucky to have a wide variety of this natural wonder! How much a geode is worth depends on what kind it is. The following are some of the most notable ones you can find here:

  • Agate geodes
  • Amethyst geodes
  • Blue Agate geodes
  • Blue Chalcedony geodes
  • Chalcedony geodes

Additional areas you should try

Our recommendations above that say “county wide” may be too broad for you, so we’re also sharing with you below the areas in those counties where you’ll surely find geodes.

Rivers and Riverbanks

Rivers and riverbanks are great areas to find geodes because the flowing water can help expose geode-bearing rocks (like basalt or limestone) that might otherwise be hidden underground. When water erodes away the outer layers of these rocks, it can reveal the hollow cavities where geodes form.

Additionally, rivers and riverbanks are often situated in areas with diverse geology, so you might find a variety of different types of geodes in one spot. How cool is that?

Streams and Creeks

Streams and creeks are fantastic because they’re often located in remote, unexplored regions where geodes might be hiding just beneath the surface. Their waters can help expose the geodes by eroding away the outer layers of rock, allowing you to more easily spot them.

And just like rivers and riverbanks, you’re highly likely to find different kinds of geodes in one spot, which is always exciting!

Lake Beds

Most lake beds can be pretty secluded, which means its geode reserves might not have been well explored yet. Plus, if a lake bed was formed by a river, it’s likely that geodes have been exposed by erosion over time, making them easier to spot.

Lake beds also offer a unique range of rock types that may be different from what you’d find in a river or creek. This means that you’ll have the opportunity to find a whole new variety of geodes that you might not have come across before. If you’re after a unique find, this is where you should go!


Quarries can provide access to rocks that are typically found deep underground. These rocks may have unique geode formations that are unlike the common ones. Plus, since quarries are usually actively mined, they can be constantly exposing new layers of rock, giving you a better chance of finding geodes that have been hidden away for millions of years.

If you’re lucky, you might even be able to get permission from the quarry owner to search for geodes in areas that are off-limits to the general public.
