Walker Valley is a rockhound paradise, especially if you’re interested in finding agates. The area is rich in Agates, Jasper, and Petrified Wood deposits.

There are three main deposit areas in Walker Valley. 

  • The Junior Agate chalcedony seam is the largest and most productive. It yields beautiful specimens of chalcedony in a variety of colors.
  • The Blue Candy is smaller but still produces some stunning pieces of chalcedony. It often gives blue or green hues.
  • The Fly-by-Nite deposit is the smallest of the three. It is still worth checking out for its rare and unique minerals.

Here’s a pro tip: go early in the season before the area gets too crowded. The best rocks are near the creek beds, so bring a shovel and a bucket to collect your treasures.

So, if you’re looking for a great place to start rockhounding, Walker Valley is the place for you!

The Ginkgo Petrified Forest is an excellent place for rock-hounding! This forest is home to various petrified wood, including ginkgo, fir, and spruce. The forest is also great for finding Agates, Jasper, and Petrified Palmwood.

The park is located along the Columbia River near Vantage in Central Washington, off Interstate 90. The park is open year-round from 10 am to 5 pm, and there are plenty of hiking trails to explore. 

When visiting the Ginkgo Petrified Forest, quick tips are to:
