A team of scientists have unearthed a Pleistocene-era Columbian mammoth trackway at Fossil Lake, Oregon. The fossilized footprints are about 43,000 years old and include tracks left in the volcanic soil by adult, juvenile and infant mammoths. There are 117 footprints, a large enough number and wide enough range of ages that studying the track will lend new insight into how mammoths interacted with each other as a herd.
