Jasper has been found in many locations in Idaho. Some of them have become popular enough to be widely known. These include Owyhee, Willow Creek, Graveyard Point Plume, and Prudent Man Jaspers.

The most famous jasper from Idaho is Bruneau Jasper, mined in Bruneau Canyon in Owyhee County. Its typical color range is from brown to brownish cream and red to reddish cream, marked with sweeping curves and ovals. The jasper precipitated within the gas cavities, fractures, and breccia voids of several rhyolite flows. It is very colorful and nicely patterned. It is not unusual to see slabs the size of a person’s hand sell for $100 or more.
