Merced man sees Virgin of Guadalupe in football-sized rock

Nobody can say why the Virgin of Guadalupe would appear on an unassuming piece of rock formed millions of years before the birth of Jesus Christ, but David Nunez says the image is unmistakeable -- a bluish-black stain on the football-sized rock clearly outlines what looks like the Holy Mother.

Nunez's father found the partially-buried boulder while looking for landscaping rocks in an Oakdale orchard. Nunez and his father -- both Catholics from Merced -- say it’s hard to dispute that the image looks like a famous image of the Virgin of Guadalupe.

"Everybody thought it looked like a turtle shell, but once he brought it home, we saw a figure on it," Nunez said. Friends have told him it's a miracle.

Father Harvey Fonseca, of Livingston's Saint Jude Thaddeus Roman Catholic Church, isn't so sure.

He recalled a time when a window in Livingston had streaks that also appeared like the virgin.

"People see what they want to see," said Fonseca, who had not examined the rock. "It's usually just a coincidence when something looks like something else. For me, it would have to be a great likeness. Then again, God is the one who makes mineral formations, so if he chooses to have an image appear on a rock, he can do it."

The rock is a 14-pound caramel brown and chalkboard black hunk of gneiss, a banded metamorphic rock that started out as sandstone and shale, according to Rob Rogers, a professor of geology at Cal State Stanislaus in Turlock. Rogers didn't examine the rock personally but reviewed several photos e-mailed to him. The original sandstone and shale were deeply buried and subjected to high amounts of heat and pressure, likely when today's Sierras were formed between 40 and 140 million years ago, Rogers said. The rock's rounded edges suggest that it was moved by water from the mountains into the Valley, probably during a flood event in the last 3 million years, Rogers said.

The Virgin of Guadalupe is said to be an image of Mary, the mother of Jesus Christ. According to Catholics, Mary appeared to a Mexican peasant named Juan Diego in the 16th Century. To prove it was a miracle, her image then appeared on Diego's cloak. People say that subsequent appearances of the image are some kind of religious sign.

Historically, appearances of the Virgin of Guadalupe are associated with hope and healing, said Max Hallman, a professor of humanities at Merced College.

"With all the economic problems and stress in our area, some may interpret it as a hopeful sign," he said.

Like Fonseca, however, Hallman points out that people will see what they're inclined to see.

"Culturally, people in India may have seen a Hindu goddess on it. If you've never heard of the Virgin of Guadalupe, you wouldn't have seen it. Visions are culturally-dependent," he said.

Rogers, the geologist, said he couldn't see the image in the e-mailed photos of the rock.

"I must lack imagination," he said.
