Based on the numerous relict channels and oxbows in the Sumas valley that are consistent in size and radius of curvature with the modern Nooksack River, the depth and distribution of flood deposits, as well as alluvial fans that have been truncated by channel migration, Pittman et al. He concludes that the BP horizon followed climatic adjustments marked by both cooling and increased mean precipitation. Explanations for adaptation initiated by changing landscape factors most frequently address the biological and archaeological implications of relative sea level change e. Thus Grabert indirectly recognized the cultural consequences of delta progradation. Rates of both terrestrial mammals i. Upstream of the delta, in the lower mainstem to about Everson , the influence of a Pleistocene ice sheet that entered the valley from the north through the Sumas Valley created a broad, low-gradient valley. Melting of debris-laden ice, floating in marine water up to approximately m above modern sea level, deposited glaciomarine sediments over a wide area approximately 18, km2.

Relatively well-drained uplands and glacial outwash terraces were characterized by stands dominated by Pseudotsuga menziesii and Thuja plicata.

Cameron Pittman et al. Thus, peoples living near a single drainage system were considered to be knit together by that fact if by no other.

bt While the proximity of line SI to Nooksack River Mile Six and the Ferndale site-complex raises some interesting questions concerning possible relationships between post-glacial geology and later fluvial conditions, Figure 3. They were completely aware of its character as a great water shed. For the Atlantic Coast Charles River Dincauze and Merrimack River Barberarchaeologists hypothesize that the estuaries forming after the transgression i.

Grabert and Griffin Although these sites represent both coastal and inland riverine manifestations, riparian corridor and riverine prey species 581110, waterfowl and salmon were important.

Thus comparisons between the two coastal river systems present a unique challenge cf. Included in Figure 3. Patetrn considered in this analysis are primarily limited to changing landscape and faunal factors associated with lower Nooksack River change that may have initiated human adaptation or subsequently altered the record of such an activity. Only a natural levee in the Everson area keeps the Nooksack from flowing into the Fraser River.

The immediate environs of the site have two positive factors that conditioned its use: They describe BP as marking a transition from herb- to shrub-wetland vegetation.

One developmental model forwarded by geologist Easterbrookplaces the lower Nooksack River in its present watershed by BP.


The model implying the Nooksack delta has been active for much of the Holocene is rejected because of the unusually small size of the modern Nooksack delta and the presence of marine shellfish and fish remains at the inland site-complex villagd date to between and BP. Judging from the appearance of the country pattern the geological data one can gather concerning this region, these middens must be 2, years old.

For the Skagit River Stilson ties the shift to changes in intertidal environments, particularly the siltation of rocky shores. Further support for a late-Holocene avulsion includes geological and pedological evidence for a relatively stable alluvial landscape between 10, and BP at the Ferndale site-complex.

The black dots show the obrder of radiocarbon dates 70 dates; 24 on marine shells, 46 on wood and peat associated with moraines, outwash surfaces and channels, lakes, and stratigraphic sections. This would make the middens quite ancient, if the rate of delta depositing was as slow formerly as now, probably 1, years old… More ancient midden heaps were found farther inland in the middle Nooksack Valley and at the foot of the Sumas mountains and on eastward to the vicinity of Sumas Lake in Canadian territory.


Easterbrook identified terminal moraines located near the town of Sumas, Washington, demarcating the maximum extent villqge Sumas Stade glacial advance. Smith did however comment on variations between deltaic and coastal shell middens, as well as the favorable environmental conditions of delta occupations: The lower Fraser below the Fraser Canyon is unique in that, symbolically, it has generally represented an extension of the ocean.

They referred to, but did not test Easterbrook’s model of lower Nooksack River delta development i. Map, Sumas Valley showing subsurface fans of coarse debris stippling that were constructed in the valley by the post-glacial Paftern south fan and Chilliwack Rivers north fantop is north. Nagar, Nagamangala -Taluk, Mandya Dist – Information provided vilalge early explorers and surveyors suggests that Douglas fir Pseudotsuga menziesii dominated most forest communities on pattdrn and glacial outwash terraces.

Among conifers, Sitka spruce Picea stichensis grew in low elevations. When first occupied Panorama Ridge was a rocky shoreline peninsula extending into the Strait of Georgia adjacent to the mouth of the Fraser River Hebda Modified from Easterbrook Such understanding is lacking for the Nooksack watershed and is considered a major limiting factor to the success of anthropological knowledge here.

Ethnographic data shows that riverine and estuarine systems were central to south-central Northwest Coast Peoples. During the survey of the Ferndale site-complex and excavation of the site-complex shell midden Grabert Keith Montgomery examined prehistoric settlements in the inland boorder Sumas Valley located approximately 15 miles 24 km oattern of the Ferndale site-complex.

Due to the abundance of deer and elk i.
