Best Time for Crystal Hunting in Washington

Check current weather and road conditions before heading out, especially for remote BLM and Forest Service roads.
Where to Find Petrified Wood in Washington
Washington produces some of the finest petrified wood in the world. The Ginkgo Petrified Forest in Kittitas County preserves over 50 species of Miocene-age trees — the greatest diversity of petrified tree species at any single locality. The wood was buried by the Columbia River Basalt Group lava flows 15 million years ago and silicified by groundwater percolating through the basalt.
Top sites:
- Ginkgo Petrified Forest State Park, Kittitas County — Museum and interpretive trails with petrified logs in situ. Collecting is prohibited in the park.
- Saddle Mountains / Beverly area, Grant County — Petrified wood on BLM land adjacent to the state park. Surface collecting allowed for personal use.
- Ellensburg area, Kittitas County — "Ellensburg Blue" agate and petrified wood in gravel deposits. Famous for blue agate — see specimen maps.
Washington petrified wood includes ginkgo (extremely rare — most is protected), maple, elm, cypress, and walnut. The material is agatized (silica replacement) and takes a high polish. Colors range from brown and tan to red and occasionally blue. Collect from BLM land outside park boundaries. Dense, heavy stones with visible wood grain in creek gravels and surface deposits are your targets.
Where to Find Jasper in Washington
Washington produces diverse jasper varieties from the volcanic terranes of eastern Washington and the Cascades. Ellensburg Blue agate (actually a blue-gray chalcedony) is the signature material, but red jasper, green jasper, picture jasper, and orbicular jasper also occur throughout the state's volcanic geology.
Top sites:
- Walker Valley, Skagit County — Jasper, agate, and fossil wood on private and public land. The WSMC (Washington State Mineral Council) manages collecting access. Check current rules.
- Ellensburg area, Kittitas County — Ellensburg Blue agate in gravel deposits. This material is local to a small area and highly collectible.
Ellensburg Blue is a translucent blue-gray to cornflower-blue chalcedony unique to the Kittitas Valley area. It is highly prized and increasingly difficult to find. The blue color is caused by the Tyndall effect (light scattering by submicroscopic particles). Eastern Washington jasper (red, green, banded) is more abundant and found in creek gravels throughout the Columbia Plateau.
Where to Find Garnet in Washington
Washington produces almandine garnets from the metamorphic rocks of the North Cascades and the Blue Mountains. The Red Top Mountain area near Cle Elum (Kittitas County) is the most popular collecting site — large almandine garnets in serpentinite and schist weather out of the rock and accumulate in the soil.
Top sites:
- Red Top Mountain, Kittitas County — Garnet in serpentinite. Okanogan-Wenatchee National Forest. Surface collecting — garnets erode out of the bedrock and concentrate in the soil and gravel. Some crystals exceed 1 inch. Moderate hike. 4WD recommended for the access road.
Red Top garnets are dark red almandine, dodecahedral crystals, and range from small (1/4 inch) to large (1+ inch). Screen the soil with a classifier — the garnets are dense and settle to the bottom. Most are fractured internally and not gem quality, but occasional transparent stones occur. The site is on National Forest land and is free to access.
Washington Rockhounding Laws & Public Land Rules
BLM Land
Washington has limited BLM land (approximately 400,000 acres). Recreational collecting is allowed for personal, non-commercial use.
National Forests
Okanogan-Wenatchee, Gifford Pinchot, Mount Baker-Snoqualmie, Colville, and Olympic National Forests allow collecting for personal use.
State Parks
Collecting is prohibited in most Washington state parks. Ginkgo Petrified Forest State Park specifically prohibits collecting. Check individual park rules.
Collection Limits
BLM: 25 lbs per day plus one specimen. National Forest: casual use provisions.
What's Protected
Mount Rainier, Olympic, and North Cascades National Parks prohibit all collecting. Mount St. Helens National Volcanic Monument has restricted collecting areas — check current rules.
Washington has two distinct collecting zones: the wet west side (beach agates, Walker Valley, Cascades minerals) and the dry east side (petrified wood, Ellensburg Blue, jasper). The east side is more productive for agate and petrified wood. Red Top Mountain is the best free garnet collecting in the Pacific Northwest. Snow closes mountain access roads from October through May.
