On Capt. Maguire’s map[N9] this lake is laid down by the name “Taso´kpoh” “from native report.” It is represented as lying between Smith Bay and Harrison Bay, and connected with each by a stream. Maguire seems to have heard nothing of Ikpikpûñ. This lake is not mentioned in the body of the report. Dr. Simpson, however,[N10] speaks of it in the following words: “They [i.e., the trading parties when they reach Smith Bay] enter a river which conducts them to a lake, or rather series of lakes, and descend another stream which joins the sea in Harrison Bay.” They are well acquainted with the Colville River, which in their intercourse with us they usually called “the river at Nĭ´galĕk,” Nĭ´galĕk being the well known name of the trading camp at the mouth. It was also sometimes spoken of as the “river of the Nunatañmiun.” The Mackenzie River is known as “Kupûñ” (great river). We found them also acquainted with the large unexplored river called “Kok” on the maps, which flows into Wainwright Inlet. They called it “Ku” (the river). The river “Cogrua,” which is laid down on the charts as emptying into Peard Bay, was never mentioned by the Point Barrow natives, but we were informed by Capt. Gifford, of the whaler _Daniel Webster_, who traveled along the coast from Point Barrow to Cape Lisburne after the loss of his vessel in 1881, that it is quite a considerable stream. He had to ascend it for about a day’s journey--20 miles, according to Capt. Hooper[N11]--before he found it shallow enough to ford. [Footnote N9: Parl. Rop., 1854, vol. 42, opp. p. 186.] [Footnote N10: Op. cit., p. 265.] [Footnote N11: Corwin Report, p. 72.] CLIMATE. The climate of this region is thoroughly arctic in character, the mean annual temperature being 8° F., ranging from 65° to -52° F. Such temperatures as the last mentioned are, however, rare, the ordinary winter temperature being between -20° and -30° F., rarely rising during December, January, February, and March as high as zero, and still more rarely passing beyond it. The winter merges insensibly by slow degrees into summer, with occasional “cold snaps,” and frosty nights begin again by the 1st of September. The sun is entirely below the horizon at Point Barrow for 72 days in the winter, beginning November 15, though visible by refraction a day or two later at the beginning of this period and a day or two earlier at the end. The midday darkness is never complete even at the winter solstice, as the sun is such a short distance below the horizon, but the time suitable for outdoor employments is limited to a short twilight from 9 a.m. to 3 p.m. There is, of course, an equal time in the summer when the sun is continually above the horizon, and for about a month before and after this period the twilight is so bright all night that no stars are visible.
