BRIDGEVILLE, CALIFORNIA—Scott Bauer of California Fish and Wildlife discovered an ancient village while investigating a marijuana-growing operation. Today’s growers are looking for the same things that Native Americans wanted in a settlement or camp site: southern exposure, warm weather, and water sources. “The activity of the marijuana cultivation out there damaged what had been a pretty large archaeological site. Now, it’s just kind of a big jumbled mess,” he said. Among the artifacts he found were a broken pestle and a broken spear head.
