Light rain, soon changing to sleet, and then frequent snow squalls, provided the principal weather elements on September 20; wind light to strong, west to north; temperature, 27° to 43.5°. The ground became partly covered with snow. A big buck, followed several hours later by a doe and a fawn, swam across to the north side of Windy River at its mouth. Ten more Caribou were taken by Anoteelik. Charles considered that the retrograde movement to the north was definitely under way. There had been indications of it on various days from September 6 on. Except for a few snow flurries, it was largely sunny on the 21st; wind brisk to moderate, north to northwest; temperature, 26° to 34°. About a quarter of an inch of snow remained in sheltered places. A doe and a fawn appeared near camp. There was considerable snowfall on the 22nd; wind light to moderate, westerly; temperature, 30° to 33°; ice in edge of the river. A large buck left tracks in the snow along the Windy River. September 23 was partly cloudy; wind brisk, north-northwest; temperature, 21° to 32°; about a quarter of an inch of snow on the ground, and a tundra pond mostly frozen over. Several small groups of Caribou (a doe and a fawn; three does and two fawns; and three others) appeared on the near-by ridges. September 24 was mostly cloudy; wind moderate to brisk, northerly; temperature, 26° to 41°; nearly an inch of fresh snow on the ground. About 15 does and fawns were resting or feeding quietly on the east side of Little River, and tracks of about half a dozen were noted on Camp Ridge. Charles Schweder reported about 50 Caribou, in three slightly separated bands, appearing during the evening on the south side of Windy River about 2 miles above its mouth, as if contemplating a crossing. He thought they may have been alarmed by Wolves. September 25 was a cloudy day; wind moderate to light, northerly to westerly; temperature, 31° to 36°; open ground largely bare by afternoon; ice forming on Windy Bay. Some Caribou tracks were noted on the north side of Windy River. There were clouds, a sprinkle or two of rain, and a little sunshine on the 26th; wind brisk to moderate, southwest to west; temperature, 36° to 47.5°; ground becoming practically bare. Three Caribou were seen beyond Little River, and a doe and a fawn on the south side of Windy River. The 27th was mostly cloudy, with a thick snow flurry; wind brisk, northwest; temperature, 33° to 40°. Two tundra ponds, previously frozen, were mostly open. Three bucks, a doe, and a fawn were noted on the south side of Windy River. September 28 was mostly cloudy; wind brisk to light, north-northwest; temperature, 28.5° to 40°; a little snow on the ground disappearing. Seven large bucks (six in one band, moving northward) passed over Camp Ridge, and a dozen other Caribou (including does) were seen beyond Little River.
