Geometric designs at Pyramid Lake at least 10,000 years old

“PYRAMID LAKE, Nevada — Ancient rock etchings along a dried-up lake bed in Nevada have been confirmed to be the oldest recorded petroglyphs in North America, dating back at least 10,000 years.

“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.”
