major changes. Glaciers, meltwater, swaying coastlines, a significantly lower sea level, tsunamis shaped this phase, and there were also uplifts and lowerings of the coastlines, which were triggered by the melting of the huge ice masses. With that, many artifacts should be gone for good. This probably explains, at least in part, why there are hardly any artifacts from before about 8000 BC, except in places that have never been flooded. Artifacts dating back to the 9th millennium BC were found on Dundas Island, at Far West Point. One of the oldest sites in British Columbia was found near Namu. The region was settled between 8000 and 3000 BC. It was inhabited by semi-sedentary and sedentary groups who processed coarse-grained effusion rock into tools. Recent studies suggest the use of watercraft. Traditionally, the Coast Salish have assumed that they have always lived where they live today. Creation stories are widespread, often of animals in human form, of creators or ancestors of today's tribes. In addition, there is the idea of ​​a (transformer) who created the landscapes, the animal and plant inhabitants, the foundations of the social order. Often they contain memories of the immigration period and of a great flood. From the Milliken phase (ca. 7500 BC) The Stó:lō also assume that they have always lived where they are today live. The Milliken Phase (7500-6000 BC) is the oldest archaeologically tangible period. The only locality is 4 km above Yale. Leaf-, egg-, and crescent-shaped blades, burins, thin scrapers, and soapstone are distinctive of this period. Argillite was the most widespread stone material, while basalt, quartz and obsidian were rare. Some charred cherry pits are an indication of the time of year that people inhabited the area. Since this is also the time of the salmon migration, it can be assumed that the salmon migrations - which were not so extensive at the time - were already being taken advantage of. Some obsidian pieces came from Oregon, 400 miles away, indicating that there was extensive overland trade. The Mazama Phase (6000-4500 BC) - named after the largest known volcanic eruption that left what is now Crater Lake in Oregon – is also tangible at Yale, but also at Hope. Innovations include egg-shaped hand axes, planes and bipolar wedges. Microliths are detectable, i.e. tiny stone blades. Basalt displaced the argillites. In this period, cultural differences between the north, which is more closely
