Where to Find Agate in Arizona
Arizona agate concentrates in the central and western deserts. Saddle Mountain in Maricopa County is the type locality for Arizona fire agate, a brown chalcedony with iridescent goethite films that flash red, green, and orange when oriented correctly. The Black Hills agate field east of Safford in Graham County yields red and yellow banded chalcedony, and the Burro Creek wilderness boundary in Mohave County produces flame-and-fortification agate in rhyolite. Round Mountain rockhound area near Duncan is the state's main BLM-designated agate collecting site. Petrified Forest National Park is closed; all collecting is on adjacent BLM ground or private leases.
