Pechanga representatives, who knew the site might have artifacts, were observing the crews’ work when the pieces were found. The Soboba tribe’s cultural resource office has since taken over monitoring the site, said Carol Gaubatz, a program analyst at the state Native American Heritage Commission, which helps protect ancient Indian sites. “You’re living in a place that’s been inhabited as long as 12,000 to 15,000 years. You’re going to find a lot” of artifacts, Gaubatz said. CORONA, Calif. – More than 100 Luiseno Indian artifacts – including 500-year-old bowls and arrowheads – were unearthed by a construction crew at the Canyon Oaks housing development. “It was almost a treasure trove out there. To have that many in one location and buried down … it was a very unusual event,” said Jim Fagelson, Riverside County’s principal planner. The artifacts have added to the Pechanga Band of Luiseno Indians’ collection. The KB Home crew was grading the area near Corona when the items were discovered, developer spokeswoman Cameron Triebwasser said. Workers had to grade in 6-inch increments after that with tribal monitors watching the process in August and September.
