Cynthia Wilson, the Traditional Foods Program director of the Utah Diné Bikéyah, washes freshly picked potatoes at Red Butte Garden in Salt Lake City Wednesday, Nov. 22, 2017. The species of potato, Solanum jamesii, has been used by native Utahns intermittently for more than 10,000 years and is the earliest known potato from the Four Corners region. Researchers at the Natural History Museum of Utah and Red Butte Garden discovered potato starch residue in the crevices of a 10,900-year-old stone tool in Escalante, Utah, which revealed the earliest evidence of wild potato use in North America.
