The crack itself, looking like a jagged bolt of crystal-white lightning, zips across the ice with the flick of a lizard’s tongue. But it is the sound of the crack, the plaintive, anguished moan, that penetrates a man and makes his skin crawl, reminding him that if the earth wanted to swallow him up, well, it could. And no one could stop it. Wyoming game warden Joe Pickett froze with the sound and looked down at his feet as the crack shot between them. The sound washed over and through him. The crack itself was no danger to him. Ice shifted and buckled all the time. Nevertheless, he sidestepped over the crack before continuing. The ice fishermen were still a quarter of a mile away across the surface of Dull Knife Reservoir in the Bighorn Mountains. Four fishermen, two sitting on upturned plastic buckets, two standing near their holes in the ice. All bundled up like black snowmen, their shapes rounded and without angles because of the thick winter parkas and insulated coveralls they wore.
