By day, the sun danced across an icescape dotted with harp seal mothers and pups with cloud-soft fur, obsidian eyes, and charcoal noses.

KINNGAIT, NUNAVUT, Canada — Just 125 miles shy of the Arctic Circle, in a hamlet etched into an icescape of rock and snow, a tiny figure clutching worn colored pencils sprawls atop a huge drawing, her frame half the size of the paper.

He spent 78 days on the icescape leading an expedition to map the geology and document the creatures and plants fossilized in Jurassic-age rocks to better understand how the ancient supercontinent Gondwana broke apart.

The entire icescape has changed.

He said he enjoys the sounds of the nearly barren continent more than anything — his skis on the snow and ice, the wind streaming across the icescape.
