At sunrise we emerged from our down-filled sleeping bags into the fog of our icy breath. We hustled from our lean-to into a 9-by-9-foot canvas tent. I laid a handful of birch bark and spruce twigs inside the stove. The snap of the match flame leaping to life always seems like a miracle while winter camping.
In the dim light, we leaned over the stove to warm our numbed fingers. Once the fire burned with more vigor, we crunched our way down to the frozen river.
With an ax, I began chipping a hole in the ice to fetch water for a pot of strong coffee. I paused and noticed something on the toboggan trail we made the previous afternoon.
A perfect wolf print was etched on our trail. Ben pulled off his mitt and held outstretched fingers over the crystalline track. It was a perfect fit.
"Whoooa," Ben whispered. "This was made last night."
I pointed to more tracks and explained there are 2,000-plus wolves living in Minnesota.
The eyes of Ben and Daniel widened at the realization that wolves had trotted past our sleeping quarters where we lay all night.
Neither Ben nor Daniel had ever seen a wolf track. Then again, neither had been winter camping before. The two brothers were experienced outdoorsmen, but they were used to the tamer wilds of the southern Adirondacks in New York state.
