Ever wonder about the meaning of the pictograph and petroglyph panels left throughout Utah by ancient tribes? What do those spirals, bleeding serpents and humpbacked flute-players mean?

The secrets of some of this art may be disclosed May 14, with the first of an expected series of workshops on possible meanings of rock art. Held at Fremont Indian State Park, the workshop will be taught by LaVan Martineau, author of the book, "The Rocks Begin to Speak."Martineau has made a lifelong study of rock art, not only in the Southwest but also in other countries, said Park Superintendent Gordon W. Topham. Under contract with the Paiute Tribe, Martineau compiled a report on the abundant rock art around the museum in Clear Creek Canyon.

The report includes an inventory of rock art sites and lists possible meanings of the paintings and chipped-in designs.

The number of participants in the workshop will be limited, and the project involves "some mildly strenuous hiking," said Topham. A lecture will be conducted indoors.

Reservations, at $20 each, should be made as soon as possible, he said.

Those interested can call Topham at 527-4631 or write to him at Fremont Indian State Park, 11000 Clear Creek Canyon Road, Sevier UT 84766.
