From the website:
A search for gold in the Arizon desert has turned up something that's inspirational as well as valuable. Burton Klatt, of Sun City, has been digging for the yellow stuff for years and has cases showcasing the nuggets he's found.
However, getting more attention than the rest is one nugget that he said is shaped like the Virgin Mary holding the baby Jesus. At first, he thought it looked like a horse. His wife was the one who spotted the holy shape.
