Under Burro Creek Bridge: Pink Agate Rockhounding in Mohave County, Arizona

Updated June 2026

Burro Creek is a Mohave County agate landmark, with Mindat recording both the Burro Creek agate occurrence and agate in the Lower Burro Creek Wilderness Area. The site is especially useful for lapidary collectors because the material is colorful chalcedony-family float tied to a well-known BLM desert drainage, not a vague county-wide agate listing. Reported finds include pink agate. Below: coordinates, access notes, nearby spots, and trip-planning links.
