Back in 2008, archaeologists discovered a set of rounded stones in the high desert near the Great Sand Dunes National Park in Colorado. They thought that the stone tools were used to grind nuts and seeds – but intriguingly, the stones didn’t have the right grinding marks.
Fast forward a decade, when archaeologist Marilyn Martorano identified them as something else completely … they’re actually musical instruments!
Brad Turner of Colorado Public Radio has the story:
The stones were clearly shaped by human hands but didn’t have the right wear marks around the edges to indicate they’d been used for grinding. So she set out to find a better explanation. About a decade later, Martorano believes she’s identified some of the earliest musical instruments ever played in Colorado.
“You really have to hear them,” said Martorano, who grew up in the San Luis Valley where the dunes sit. “That’s when you believe it.”
