It appears likely that the higher elevations may serve for the nocturnal rest as well as for a noonday siesta. During the evening of June 1, for instance, some 75 Caribou in a loose aggregation were feeding over the summit of Josie’s Hill, beyond the junction of Windy and South bays. On June 20 I was enjoying a wonderfully clear and golden light that was cast on the imposing mass of this hill as the sun was setting at my back about 9 o’clock. The glory of that scene was enhanced by picking out with the naked eye, at a distance of a couple of miles, two separate bands of 12 to 15 Caribou making their way upward toward the broad, plateaulike summit. Meanwhile a lone Caribou was outlined against the sky on one of the rocky ridges to the south. Might not these various movements have indicated a common urge to spend the semi-darkness of the Arctic summer night on some high, open area where a good lookout for Wolves could be kept? About 2 p.m. on June 15, a herd, perhaps half a hundred strong, appeared on a ridge directly across the river from camp. The animals made a lovely spectacle as they stood for a time, despite certain human movements in camp. Then they moved off upstream. A couple of hours later about 15 Caribou were feeding quietly on the south bank. On the following morning a band of 20 were doing likewise in nearly the same place. Among them were a patriarchal buck (apparently the leader), several other bucks, various does (one with hard horns), and a large proportion of yearlings. The bucks in general were lighter in color--more buffy; the does and yearlings, a sort of smoke gray. They seemed to be feeding to some extent on the patches of crowberry and dwarf birch. Presently they trotted off upstream, almost but not quite in single file, for a couple marched out of line with the others. On June 17 a band of about 20 appeared at a distance of 125 yards on the brow of a low hill near Stump Lake. Nearly all were big bucks, with velvety antlers up to about 20 inches in length. Perhaps three in the band were hornless--if not does, then young bucks that had very recently shed their antlers. Two of the bigger bucks were in the lead. At first the band came toward me, then went off at a tangent at a good pace, splashed across a little stream in a spirited action, and disappeared over the next ridge. Out of several bands appearing on June 20 on the opposite side of the river, one of about 14 individuals came down the slope near the mouth, took to the water at once, and made for the north shore. A strong buck landed first, and farthest upstream; others did nearly as well, but some of the smaller animals were swept by the strong current down into the bay and probably landed beyond the point. On reaching the shore, and even some minutes afterward, several of the Caribou could be seen shaking the water from their fur in doglike fashion.
