Where to Find Jasper in Washington
Washington jasper concentrates around the Saddle Mountains and the basalt country of central Washington. The Saddle Mountains in Grant and Kittitas counties yield picture jasper, brown landscape jasper, and brecciated patterns in basalt flow tops. Lake Lenore and the Sun Lakes area add red and yellow jasper float on the coulee floors. The Yakima Canyon and Ginkgo Petrified Forest area (the park itself closed to collecting) carries jaspered petrified wood in the same basalts. Most jasper is float on rim-rock slope wash, and the better cabbing material concentrates in dry washes after winter storms strip surface dust.

Hand-picked from the full list below, with the reason each one earns a trip.
Crescent Beach
Clallam County County
Agates were once plentiful enough at Agate Bay, just west of Crescent Bay on the Strait of Juan de Fuca, to give the beach its name, and agate still weathers from the local basalt alongside variously colored chert and jasper. The setting on the northern Olympic Peninsula makes it one of the few documented agate beaches on the strait.
Moclips
Grays Harbor County County
The beach at Moclips lies within Washington's Seashore Conservation Area, documented in rockhounding guides for the agate and jasper that wash in along the tideline and stream gravels. State ocean beach rules allow small-scale collecting year round, so loose agate and jasper can be picked up for personal use. Material concentrates near the low-tide line after winter storms expose fresh gravel.
Pe Ell
Lewis County County
The Washington Geological Survey's gemstone report records that hundreds of pounds of agate have been taken between Adna and Pe Ell, in the heart of Lewis County's carnelian-agate country. Carnelian, the local red-orange chalcedony, occurs with agate, jasper, and dark petrified wood in the stream gravels. Most of the surrounding Willapa Hills is gated private timberland.
