The petroglyphs found on limestone boulders near Pyramid Lake in northern Nevada's high desert are similar in design to etchings found at a lake in Oregon that are believed to be at least 7,600 years old. Unlike later drawings that sometimes depict a spear or antelope, the carvings are abstract with tightly clustered geometric designs - some are diamond patterns, others have short parallel lines on top of a longer line.
Scientists can't tell for sure who carved them, but they were found on the Pyramid Lake Paiute Tribe's reservation land.
