Researchers have known about the well-preserved footprints near Çakallar volcano, in Turkey, since the 1960s. But assigning a date to these prints has been challenging. In a new study, researchers found that the prints were made during the Bronze Age, about 4,700 years ago.

Researchers take a breather at the top of Çakallar volcano in western Turkey. During this particular field study, they were doing cosmogenic chlorine exposure dating, which allowed them to measure how long the volcanic rocks have been sitting near the Earth's surface.

Hikers and artists
This depiction shows Bronze Age people leaving their footprints in the volcanic ash and then later illustrating the volcano's massive eruption on a rock shelter about 1.2 miles (2 kilometers) away. The prints indicate that these ancient people were walking with staffs.
Ancient rock art
From left to right: Ancient humans painted this illustration on a rock shelter, just a 20-minute walk from where Bronze Age human footprints were found in volcanic ash; a color-enhanced version of the rock art, which enhances the cone-shaped feature, the lower elongated line, the three-fingered handprints and other details; a reconstructed version of the painting.

Toes to heel
One of the ancient human footprints at the site. This footprint is embedded in a layer of volcanic ash. Soon after it was left, it was covered by scoria, a volcanic rock with a frothy texture, which is why this print was preserved for thousands of years.
