REASON to WALK the FROZEN TRAIL
Ninety percent of the Norse Greenlander's food was from seals. The seals, which thrive in open water, were best harvested at the edge of the ice. When the climate turned cold, the ice formed over Davis Strait, taking most of the seals too far south.

The desperate Norse hunters walked to the open water marvels to get food to take home to their families. As the cold persisted through two generations, the thought of moving the families to the food became compelling.
