A television documentary about Nevada's "rock art evangelist" and her campaign to preserve Nevada's history in stone is scheduled to air 8 p.m. Thursday on KNPB Channel 5.

Such sites are increasingly being compromised by expanding urban areas, putting the rock art in danger of destruction by people who deface or remove the carvings (petroglyphs) and paintings (pictographs).

Woody became nationally known as Nevada's "rock art evangelist" and dedicated her career to protecting such sites. The 51-year-old archaeologist, anthropologist and professor at the University of Nevada, Reno died in July.

Independent filmmaker Gwendolyn Clancy, who produced and narrated the project, said the film is a fitting tribute to Woody's work and the efforts of the Nevada Rock Art Foundation, which continues her preservation efforts.

The film received major funding from the Nevada Department of Cultural Affairs and features interviews with Woody, former Bureau of Land management archaeologist Pat Barker and Ben Aleck of the Pyramid Lake Paiute Tribe.

DVDs of the film can be ordered from Nevada Rock Art Foundation and proceeds will benefit the Alanah Woody Fund. The foundation can be reached through its Web site, www.nevadarockart.org, or at 323-6723 in Reno.
