Standout chalcedony spots in Arizona

Hand-picked from the full list below, with the reason each one earns a trip.

1 mi. N of old Three-Way drive-in theater
Greenlee County County
Black Hills is one of Arizona's clearest public fire-agate localities, with BLM stating that fire agate is the principal attraction and that the site is open for public digging without fees or permits. The locality stands out because the collecting target is specific, chalcedony with opal-like color play in volcanic deposits, and the land manager publishes both access and collecting context.
Area near Meadow Creek Pass
Mohave County County
Meadow Creek Pass belongs to the same western Arizona volcanic-desert collecting belt that gives Mohave County its agate, chalcedony, jasper, and fire-agate reputation. It earns a place because the material suite is broader than a single color of agate, while BLM's Arizona guidance specifically flags fire agate on Kingman Field Office public lands.
