In 2014, a glacier archaeologist in Norway was dispatched to Mt. Digervarden in Reinheimen National Park in search of artifacts ceded by melting ice. Within minutes of arriving onsite, he found an Iron Age arrowhead. Shortly after, he uncovered one from the Bronze Age.
Turning in for the evening, he spotted something of far greater significance: a piece of wood protruding from the rocks that was actually a medieval ski which had been preserved in the ice for 1,300 years.
