In late winter and early spring, our Inupiat friends in Point Hope began talking about “breaking trail” across the frozen Chukchi Sea so that snow machines (snow mobiles) and hondas (ATVs) could be driven out to leads (open lanes in the ice) in order to set up whaling camps. “Breaking trail?” Informed by our experiences with freshwater lakes, we wondered, “Can’t you just drive out across a smooth blanket of ice?”

Well, as we learned, a frozen sea isn’t like that. As ice forms and expands and is pushed around by winds and currents, sheets separate (creating leads) and later are pushed together again, the resulting pressure ridges can heave up massive jumbles of jigsaw ice. Some of the chunks are as large as a garage. This was all new to us the first time we hiked out to a camp. In the above photo our eyes are drawn to an otherworldly sphere and pyramid lit blue in pre-dawn light.
