Unusual discovery: Wildlife biologist Kevin White, left, of the Alaska Department of Fish and Game, discovered last fall that a black bear was wearing a GPS collar White had put on a mountain goat almost a year earlier. A map, below, shows a cluster of dots near the terminus of Meade Glacier at the Katzehin River. The red dots are goat locations logged before July 4; the blue dots indicate the bear's movements after that time. Points are generally logged every six hours. After acquiring the tracking collar, the bear moved south into the upper headwaters of the Lace River, then crossed the Meade a couple of times, visiting the nunatak, an "island" of rock with some alpine vegetation, surrounded by ice. In the fall the bear returned to the north side of the Meade to den up for winter, near where it first acquired the collar.
