Back when I taught at Adams State College in Alamosa, Colorado I used to go hiking around the Great Sand Dunes National Park. It’s an interesting area, right next to the Sangre de Cristo Mountains in the San Luis Valley. The sand dunes are formed by wind, rather than water. The area was also the home to Native Americans from at least 5,000 years ago. Stone tools discovered by archeologists decades ago were perplexing because while they were clearly made by humans, they didn’t have the correct wear marks on them to indicate that they were used as tools for grinding.
Enter archeologist, Marilyn Armagast Martorano. She spent years examining these rocks without coming up with a good explanation. Then someone sent her a video showing lithographs, musical stones. It dawned on Martorano that the stone tools might actually be musical instruments. As it happens, she was probably right.
If you’d like to get an idea what these stone musical instruments sounded like, watch here’s a YouTube video. Also, go to the Colorado Public Radio’s page where you can also get the chance to try them out (virtually) yourself.
