This large basalt rock was carved by ancient peoples to map the area of the upper Snake River, possibly as long as 12,000 years ago.
The map is believed to have been carved by the Shoshone-Bannock natives long before European contact. It depicts the Snake and Salmon Rivers, as well as the animals and tribes that inhabited the territories in between. No one can decisively say what the carving’s purpose was, which only contributes to its mysterious, ancient allure. Licensing and Open Edition Prints
