This time on The Children’s Hour, we explore petroglyphs with Ranger David Ottaviano from Petroglyph National Monument, and Todd Scissons, Tribal Historic Preservation Officer with Acoma Pueblo. Learn who made these ancient rock carvings, why they are so common in the desert Southwest, and what they mean to the people whose ancestors made them. Plus we find out about the Junior Ranger Program with the National Parks Service, and we hear from the kids in the Extinction Diaries about a rare and nearly extinct bird from New Zealand.
