Where to see fossils in Washington state

October 21, 2013 | Burke Museum

Washington state is home to a wide variety of fossils—from delicate flowers to bulky mammoth bones to the fossil mold of an ancient rhino. Best of all, Washington has several fossil sites that are open to the public.

Here’s a list of fossil sites and other places where you can check out Washington fossils:

FOSSIL SITES OPEN TO THE PUBLIC

Stonerose Interpretive Center & Eocene Fossil Site

Location: Republic, Washington, in the northeastern part of the state

What to see: Fossil beds from the Eocene (50 million years ago)

What to do: Dig for your own fossils!

The area where Stonerose sits was once part of an ancient lake, and plants, insects and fish fossils have all been found here, providing insight into the geologic and biologic past of the Pacific Northwest. Not only can you see these fossils at Stonerose—you can also dig for them yourself and take some of your finds home!
 

More details: For more information, check out the Stonerose Interpretive Center website, including guidelines for fossil hunting at the site and open times/days and directions.

Gingko Petrified Forest State Park

Location: Near Vantage in central Washington, east of Ellensburg and south of Interstate 90

What to see: Fossilized ancient forests

What to do: Explore the hiking trails, visit the interpretive center (weekends, holidays and by appointment only)

One of the most unusual fossil forests in the world, the Gingko Petrified Forest State Park runs along the Wanapum Reservoir on the Columbia River in central Washington. Check out the diverse collection of petrified wood and don’t forget to take in the surrounding landscape, which shows evidence of Ice Age land formations.

More details: For more information, see the Washington State Parks website and the video below in which paleontologist Kirk Johnson visits the Gingko Petrified Forest State Park and discusses how petrified wood is formed.

Be sure you know and understand the laws about trespassing and collecting before you attempt to search for fossils or collect fossils. For more information, see the Washington State Department of Natural Resources Fossil Collection in Washington page and the U.S. Department of the Interior Bureau of Land Management resources and policies about paleontology.
