The Susquehanna River Archaeological Center in Waverly will celebrate the area's Native American past for the 10th year in a row Saturday.

The annual Drumbeats Through Time event will feature two speakers and the return of the award-winning Seneca Buffalo Creek dancers. Doors open to the public for the free event at 1 p.m., said SRAC executive director Deb Twigg.

Dr. Barry Kass, professor emeritus of anthropology at Orange County Community College in Middletown, N.Y., will speak on the earliest inhabitants of the Lower Hudson Valley. Kass will tell of archaeological discoveries at the Quarry Caves site near Florida, N.Y., which turned up an array of evidence of early human occupation.

Kass gave the presentation last year before the New York State Archaeological Association, Twigg said.

At 2 p.m., the center will welcome Dr. DeeAnne Wymer, an anthropology professor at Bloomsburg University and a member of SRAC's advisory board. Wymer will speak of excavations at the Hopewell Mound Group in Ohio.

In the summer of 2012, during a joint archaeological project with the State University of New York at Geneseo, Wymer and her group turned up an encampment that had been barely disturbed since its occupation during the Hopewell period. Her presentation will unveil the group's discoveries.

The Seneca Buffalo Creek Dancers, who regularly close the event, will perform at 3 p.m., Twigg said. The dancers proudly share their history and culture and encourage the audience to participate in some of the dances.

The dancers have been a fixture of the celebration for years and have become like family to the center, Twigg said. "They have been with us for so long," she said.

The SRAC exhibit hall will also be open at no charge, and the hall will include several local private collections that are normally not on public display.

SRAC members are invited to a free membership luncheon at 11 a.m., catered by the Waverly Methodist Church. Each member in attendance will receive a commemorative mug and will be able to participate in giveaways, Twigg said.

"We really want them to know how much we appreciate their support," Twigg said. "It's just a really cool day."
