The Cariboo region comprises that section of Central British Columbia between the Fraser river and the mountains of the N. Thompson river, extending northward from Clinton to Quesnel; through it the old Cariboo trail (now a motor road) passes and railway communication with the south is afforded by the P. G. & E. Ry. Its altitude is around 2500 ft. and it consists largely of rolling, wooded country interspersed with numerous lakes; in the southwest in the vicinity of Jesmond, Mt. Bowman, a northern spur of the mountains back of Lillooet, rises to a height of about 7500 ft. The summer rainfall is slight, and the area belongs in the so-called “dry belt”.

The Way

Semi-Subterranean houses with an entrance through the roof are a well known feature of the interior of British Columbia, having been described for the Thompson, the Chilcotin, the Shuswap and others of the upper Fraser River valley. They have, in fact, an even wider distribution east of the Coast and Cascade Ranges, extending south over the Plateau and into northern California. Although this type of dwelling existed among the Aleuts, it appears that the coastal people to the south of them, even in Alaska, were either unfamiliar with the pattern or rejected it in favor of others. Sporadically, along the Pacific Coast all the way from California to Bering Sea, house floors were excavated to varying depths, sometimes even to two levels; but, everywhere, the houses characteristically lack the roof entrance and, except for sweathouses in the south and Bering Sea Eskimo dwellings in the north, even the idea of an earth covering is absent. In view of this fundamental divergence, it is interesting that subterranean structures do appear in several places on the coast of British Columbia.

XIPHINEMA BAKERI N. SP. (NEMATODA: LONGIDORINAE) FROM THE FRASER RIVER VALLEY, BRITISH COLUMBIA, CANADA

Xiphinema bakeri n. sp. is described from soil associated with the roots of raspberry and strawberry plants. The specimens were collected near Hatzic, in the South Fraser River Valley, British Columbia. This species most closely resembles X. index Thorne and Allen, 1950, but is distinguished from the latter by its greater length, longer spear, more anteriorly placed vulva, and the presence in the female of only two pairs of caudal pores.

East End

In the early summer of 1926 I spent nearly two months in the vicinity of Lillooet, B. C., a typical “dry-belt” locality, studying the insect fauna of this region. My headquarters were at Craig Lodge, at the east end of Seton Lake, a large body of water about three miles west of Lillooet draining into the Fraser River through Seton Lake Creek, which is joined about a mile to the east by the larger Cayoosh Creek, entering from the south through the deep and precipitous Cayoosh Canyon. The general nature of the country has already been ably indicated by Mr. R. Glendenning in a paper on the Fauna and Flora of Mt. McLean which appeared in the Proceedings of the British Columbia Entomological Society for 1921.

X-ray diffraction analysis was used to identify the clay minerals present in fourteen subsoil samples that were selected to represent some more important clay-bearing deposits in British Columbia. The clay mineralogy of the subsoils varied considerably but montmorillonitic clay minerals tended to predominate in the water-laid deposits of the south and illite in the soil parent materials of the Interior Plains region of the northeastern part of the Province.

Bridge River tephra: revised distribution and significance for detecting old carbon errors in radiocarbon dates of limnic sediments in southern British Columbia

Tephra Beds

Ash-grade Bridge River tephra, identified as such on the basis of shard habit, modal mineralogy, and composition of ilmenite, occurs in sedimentary cores from three lakes located to the south of the previously documented plume and necessitates a significant enlargement of the fallout area of that tephra in southwestern British Columbia.These new, more southerly occurrences are probably equivalent to the ~2350 year old Bridge River tephra, although it can be argued from the evidence at hand that the 14C dates and biotite-rich nature support relationship to a slightly earlier Bridge River event.Large differences exist in the 14C age of sediments immediately adjacent to the Bridge River tephra at these three lake sites; maximum ages of 3950 ± 170 years BP (GX-5549) and 3750 ± 210 years BP (I-10041) were obtained at Phair and Fishblue lakes, respectively, whereas the corresponding age at Horseshoe Lake is only 2685 ± 180 years BP (GX-5757). The two older dates are considered to be significantly affected by old carbon contamination for the bedrock locally consists of calcareous sedimentary rocks and the lacustrine sediments are very calcareous. The 14C date from Horseshoe Lake, which occurs in an area of igneous rocks, appears to be only slightly too old relative to the ~2350 year old Bridge River tephra.Well-dated tephra beds, therefore, can be very useful in assessing the magnitude of old carbon errors associated with radiocarbon dates based on limnic sediments. Calcareous gyttja deposits beneath Bridge River tephra within the study area exhibit old carbon errors of the order of 1350–1550 years.

Gitksan (git) is an Interior Tsimshianic language spoken in northwestern British Columbia, Canada. It is closely related to Nisga'a, and more distantly related to Coast Tsimshian and Southern Tsimshian. The specific dialect of Gitksan presented here is what can be called Eastern Gitksan, spoken in the villages of Kispiox (Ansbayaxw), Glen Vowell (Sigit'ox), and Hazelton (Git-an'maaxs), which contrasts with the Western dialects, spoken in the villages of Kitwanga (Gitwingax), Gitanyow (Git-anyaaw), and Kitseguecla (Gijigyukwhla). The primary phonological differences between the dialects are a lexical shift in vowels and the presence of stop lenition in the Eastern dialects. While there exists a dialect continuum, the primary cultural and political distinction drawn is between Eastern and Western Gitksan. For reference, Gitksan is bordered on the west by Nisga'a, in the south by Coast Tsimshian and Witsuwit'en, in the east by Dakelh and Sekani, and in the north by Tahltan (the latter four of these being Athabaskan languages).

Bed Material

The lower main channel of the Fraser River, British Columbia, is a sand-bed, salt-wedge estuary in which variations in velocity, discharge, and bedform characteristics are contolled by river discharge and the tides. Bed-material composition remains consistent over the discharge season and in the long term. Changes in bedform height and length follow but lag behind seasonal fluctuations in river discharge. Migration rates of bedforms respond more directly to river discharge and tidal fall than do height and length. Bedform characteristics were utilized to estimate bedload transport in the estuary, and a strong, direct, but very sensitive relationship was found between bed load and river discharge. Annual bedload transport in the estuary is estimated to be of the order of 0.35 Mt in 1986. Bedload transport in the estuary appears to be higher than in reaches upstream, possibly because of an increase in sediment movement along the bed to compensate for a reduction in suspended bed-material load produced by tidal slack water and the salt wedge.
