Where to Find Jasper

517 mapped jasper spots across 63 regions in 5 countries. Pick a region for its local guide, or browse every spot below. Jasper is the opaque cousin of agate: silica-cemented, often vividly colored, and tough enough to take a high polish. The American West is rich in picture jasper, brecciated jasper, and sea-deposit varieties from Oregon, Idaho, and Washington.

Where to find jasper

The best places to find jasper in the United States are the Owyhee country on the Oregon-Idaho border (home of picture jasper), the desert washes of Utah, Wyoming, and New Mexico, California's Mojave Desert and central coast, and historic jasper districts in eastern Pennsylvania. Look for opaque, vividly colored stones with a waxy shine in dry washes, gravel bars, and road cuts.

Owyhee country: America's picture jasper capital

The high desert where Oregon and Idaho meet produces the most famous jaspers in the world. Biggs jasper from the Columbia River hills and the Owyhee picture jaspers (Blue Mountain, Deschutes, Succor Creek) form scenic brown-and-blue landscapes inside the stone, and rough still weathers onto public BLM ground across the district. Bruneau Canyon in southwest Idaho grew the legendary Bruneau jasper; the historic digs are claimed, but float shows up in area gravels.

Hunt the region by walking wash bottoms and talus below jasper-bearing ridges. Fresh breaks show the color: a dull brown cobble often hides a vivid interior, so experienced hunters carry a crack hammer and check anything with the right heft and smooth fracture.

The desert Southwest and Rockies

Utah's west desert, Wyoming's basins, and New Mexico's BLM lands all scatter red, yellow, and brecciated jasper through their washes, often in the same gravels that carry agate and petrified wood. Texas adds jasper along its rivers and in the Big Bend ranch country, and Arizona's washes produce colorful material statewide.

In desert country, jasper hunting is a surface game: walk slowly, work the low sun angles, and check gravel bars after flash floods rearrange the wash. The material is tough, so it survives long transport and turns up far from its source.

East of the Mississippi: historic jasper districts

Jasper is not only a Western stone. Eastern Pennsylvania's Vera Cruz and Macungie area holds jasper quarries that Native Americans worked for thousands of years, and honey-colored jasper still turns up in the surrounding woods and creeks. Piedmont creeks in North Carolina and Georgia carry jasper pebbles alongside quartz, and the material shows up in river gravels throughout the Southeast.
