First Nations Artifacts

With the arrival of Aboriginal Day on the 21st of June, the Museum would like to shine a spotlight on the variety of early First Nations tools and artifacts that have been found in the Peace River area.
       The First Nations peoples did not work metal. Instead, they used rocks that they found already present in their natural environment to craft durable tools. Some examples include spear tips and arrowheads for hunting game, as well as scrapers for preparing hides to be used in clothing or the building of shelters.

        The rocks chosen for tool-making were not picked at random from the ground. The First Nations people would painstakingly gather special stones called chert (flint), quartzite and obsidian. These rocks do not contain planes of weakness in their crystal structure, so instead of fracturing randomly when struck, their shape could be carefully controlled. This is, of course, provided the striker possessed sufficient patience and skill. Chert and quartzite were the most common materials used, and come in a wide range of colours and hues. Considerably rarer, obsidian is a volcanic glass, and one of the sharpest known materials. It is usually quite dark and highly reflective. The obsidian scraper pictured below was likely traded from a distant region, as volcanism and its products are not typically found in the Peace River area.

Aboriginal Jadeite Adze

         As we approach the date of the Annual Aboriginal Gathering and Pow Wow, the recent donation of a jadeite adze found south of Grimshaw area by Bill Veidt comes at an opportune time.

         Jadeite is a variety of jade, a strong and hardy material characterized by its distinctive green hue. Its strength lends itself well to tool-making, though the material itself is quite rare. This adze was therefore most likely an object of great importance and prestige. The crafting of such an device was a labour-intensive process, with countless hours of sawing, cutting, grinding and polishing. The product of these efforts is a long-lasting and high-quality tool that is a testament to the skill and ingenuity of the First Nations craftsmen. The age of this adze could range from hundreds to thousands of years old. As you can see, it has withstood the test of time remarkably!
Bill Veidt
        While the majority of jadeite artifacts recovered in Alberta were found in the Peace River region, most jadeite tools are associated with the west coast of BC. This is because the First Nations peoples of BC had increased access to quarries and had developed larger-scale stoneworking and woodcutting practices relative to the more mobile people of the plains. The geology of BC is also such that jadeite, a metamorphic rock, forms much more commonly in mountainous regions raised by plate subduction. It is believed that this stone in particular came from the Fraser River Valley of BC. So, this tool was likely traded from afar and had quite a journey before arriving in the Peace Country.

         Even more ancient tools can be found in the Archaeology Case in the Peace River Gallery of the museum, including chert and even black obsidian artifacts.
