Two Native American galleries are set to open at the Louisiana State Exhibit Museum in Shreveport. They feature the Poverty Point culture and the Caddo Nation. The museum constructed a glass case to display a 30-foot long canoe constructed of a single bald cypress tree dating back 1,000 years. It was found on the banks of the Red River in 1983. A seven-minute documentary explains how it was preserved. The opening reception is Saturday, Oct. 20, from noon to 4 p.m.
