Walker Valley Geode Site
Walker Valley is western Washington's reliable geode site, and the Washington State Mineral Council holds a valid mineral lease for the locality on DNR land east of Mount Vernon — which is what keeps it legally open to collectors. Most nodules run small and open to clear quartz, but the amethyst-lined ones are what keep people coming back. Display a Discover Pass, follow the Rockhound Code of Ethics the council publishes, and fill in the council's field-conditions questionnaire after your trip — that reporting is part of how the lease stays defensible.

| What you can find | quartz geodes, amethyst geodes, chalcedony, agate |
|---|---|
| Access | Club open dig — Free with permit |
| Fees | no dig fee; a valid Washington Discover Pass must be prominently displayed in your vehicle or you may be ticketed (about $35 annual, $11.50 day) since the site sits on state DNR land |
| Season & hours | open year-round when roads allow; the access road is gated, so park clear of the road and walk around the gate — the collecting ground is less than 250 feet in. Logging operations and DNR road work close the approach periodically, so check with the Mineral Council before driving out |
| Kids | Family-friendly — the walk in from the gate is only a couple hundred feet, which kids manage easily, but the geodes come out of stiff clay and need a pick and real effort |
