NOVATO – The '60s aren't dead. They're in an archaeological site north of San Francisco.

An old commune where the Grateful Dead and other bands used to romp is being excavated and items catalogued by state park archaeologists at Olompali State Historic Park.

Among the artifacts: the classic hippie beads, a marijuana "roach clip," fragments of tie-dyed clothes, and a reel-to-reel tape a Marin County studio technician has promised to try to restore.

They are the stuff of memories for Noelle Olompali-Barton, who was 16 when she and her showbiz mom plunged into California's new counterculture, retreating to this once-private ranch north of San Francisco to establish one of the first hippie communes.

The teenager baked bread to give away in Golden Gate Park. She sat with the Grateful Dead under an oak tree for a famous 1969 album photo.

For two intense, often drug-laced years, the commune nourished utopian dreams – and some bad trips, too, she said.

But never in her wildest hallucinations did the teen imagine that more than 40 years later, she would assist an archaeologist in identifying macrame headbands, old records and other commune artifacts retrieved from the abandoned ruins of her former home.

"You know you're old when you're pictured in Archaeology magazine," chuckled Olompali-Barton, now 58, who was profiled in that journal in July along with California state parks archaeologist E. Breck Parkman.

Sitting under oaks outside the park's visitor center, Parkman laughed along with Olompali-Barton, who has been using the ranch's name as her own since she lived here.

The state of California bought Olompali in 1977, and opened a park on its 700 acres of oak-studded rolling hills.

Parkman knows some might scoff at his project to catalog and display the artifacts of an era many alive remember well – or not so well if they were especially indulgent.

But the commune, he said, is as much a part of Olompali as the rest of its history, stretching back thousands of years.

"I see the commune as part of the Cold War," he said. "If we hadn't had the Cold War, we wouldn't have had Vietnam, and if we hadn't had Vietnam, we wouldn't have had the commune. It was one of the reactions to the war."

The years the commune existed, late 1967 to 1969, were some of the most tumultuous and divisive in modern American history, Parkman said.

Prominent figures of the '60s visited the site – the Grateful Dead rented the ranch the year before the commune moved in – and hippie culture went on to have an indelible impact, for better or worse, on global culture, he said.

The commune members lived, Parkman also noted, in a historic 1911 stucco mansion that was built on and attached to an 1828 adobe of a Miwok Indian chief.

The adobe, now fully visible, is the oldest standing structure in the state north of San Francisco and a national registered historical site.

Olompali is also historically rich, Parkman said, because native Miwok Indians developed major settlements here. The park's name is Miwok, and it means "southern village" or "southern people."

After the commune members were gone, Parkman said, the land was controlled by a Jesuit order. Archaeologists excavating here in 1976 unearthed a startling find at a Miwok site: an Elizabethan silver sixpence minted in England in 1567 that could have arrived by way of Sir Francis Drake.

The commune members were generally aware of some of the ranch's heritage, including the Miwok, Olompali-Barton said. Their ethos was "get back to the land," and live simply with nature.

But acid rock was their soundtrack. And in 1969, while many in the commune were working at a rock concert light show in San Francisco, an electrical fire broke out at the mansion and gutted it.

The fire was part of a downward spiral Olompali-Barton blames on a decision to open the commune up to more than a closely knit circle of families.

"There were the freeloaders who came," she said, "who sat in the living room playing music and not helping at all."
