Sled Dogs on Ice

A Pack on Edge: Gedion drags his dogs off an ice foot, where the land meets the frozen sea. The dogs sense the ice is melting and resist. "They can smell the salt water and know it's unsafe," says author Gretel Ehrlich. Once on the sea ice, the team will pick its way around the riskiest spots.
