At Kusawa Lake, a subalpine glacier-fed mountain lake situated in the Yukon Territory (western Canada), measurements of Hg in caught fish are below, but worryingly close to, the Health Canada guideline for safe fish consumption of 0.5 µg g-1. The sources of the Hg found in the fish of Kusawa Lake (and many other northern lakes) are still unidentified. A suspected pathway for Hg input to freshwater ecosystems is through long-range atmospheric transport and direct or indirect deposition in water and/or snow-covered surfaces, later released to aquatic ecosystems through spring/summer melt and runoff. The objective of this thesis is to estimate the maximal potential contribution of atmospheric Hg released by snow- and ice melt that could enter Kusawa Lake through runoff from snow and glacier ice melt. Hg data previously obtained from the Kusawa Lake catchment were used to estimate the possible range of Hg concentrations in snow and ice. To quantify the input of Hg from snow and ice melt into Kusawa Lake, the total water inflow from these sources first had to be estimated. This was done by using the HBV hydrological model (Hydrologiska Byråns Vattenbalansavdelnings modell), initially developed by the Swedish Meteorological and Hydrological Institute (SMHI), and subsequently modified to include a glacier routine. The HBV model was run using temperature and precipitation data from the nearby city of Whitehorse (~60 km east of Kusawa Lake), and was calibrated using historical hydrometric data from the Kusawa Lake catchment itself. Using these data and the HBV-simulated runoff, the total flux of Hg entering Kusawa Lake trough snow and glacial melt water was estimated to be 550 ± 495 g yr-1 (3.6 ± 3.5 μg m-2 yr-1). This flux comparable in magnitude with model-based estimates of the total atmospheric deposition of Hg in the Yukon region, which range between 4.5 and 7 μg m-2 yr-1. This suggests that for subarctic glacier-fed lakes like Kusawa, the supply of Hg from snow and ice melt actually represents a large percentage of the total annual Hg input.

Kusawa sjön, som ligger i Yukon Territory i Kanada, är en fjällsjö vars vatten i huvudsak kommer ifrån den årliga snösmält- ningen och omkringliggande smältande glaciärer. Här har man observerat höga halter av Hg i fisk. Halterna är under Kanadas riktlinjer för säker konsumtion av fisk på 0,5 µg per g Hg men oro- väckande nära. Vad som är orsaken till detta i Kusawa sjön (och i många andra nordliga sjöar) är oklart. En möjlig källa skulle kunna vara att Hg, i gasform, transporteras till dessa platser genom globala vindsystem och kan efter kemiska reaktioner avsättas som snö i och med nederbörd eller direkt på ytan av snötäcken. När snön sedan smälter kan Hg följa med i vattendragen och slutligen hamna i dessa sjöar. Syftet med den här uppsatsen var att uppskatta hur mycket Hg som genom smältvatten från snö och glaciärisar kan årligen transporteras i vattendrag till Kusawa sjön. Arbetet använder sig av tidigare insamlad data över kvicksilverhalter i snö- och isprover i Kusawa sjöns närområde. Detta har gjorts genom att använda en avrinningsmodell, HBV, för att uppskatta hur mycket vatten som transporteras till sjön i genomsnitt varje år. Modellen tar hänsyn till både snö och glaciärisavsmältning och är baserad på meteorologisk data, så som nederbörd, temperatur och avdunstning, från den närliggande staden Whitehorse (ca 60 km öster om Kusawa sjön). Det totala flödet av THg (Total Hg, var alla typer av kemiska föreningar av Hg är inräknade), genom snö- och glaciärsmältvatten, uppskattas att vara 550 ± 495 g per år för Kusawa sjöns yta. Detta ger ett genomsnittligt flöde på 3,6 ± 3,5 μg per m2 och år, vilket skulle kunna motsvara storleks- ordningen av atmosfäriskt Hg som uppskattas avsättas varje år i regionen (7 μg per m2 och år ). Denna undersökning är den första uppskattningen och har därför ingen tidigare litteratur att jämföra med. Den använda metoden är en mycket grov och förenklad bild av de processer som sker ute i naturen men ett första steg för att undersöka varför Hg halten är så hög i den subalpina sjön Kusawa i Kanada.

In memory of Tagish ABSTRACT Recently documented ice patch sites in the southwest Yukon are ideal for evaluating precontact hunter-gatherer land-use patterns in the western subarctic. Located in the alpine of the mountainous regions of the boreal forest, ice patches are associated with well preserved hunting equipment, caribou (Rangifer tarandus) dung and an abundance of faunal remains dating to over 8000 years ago. However, current models are inadequate for explaining caribou hunting at ice patches as they tend to emphasize large-scale communal hunts associated with latitudinal movements of caribou. Much less is known about the alititudinal movment of caribou and the associated hunting forays to ice patches in the alpine.

    INFORMATION TO USERS This was produced from a copy of a document sent to us for microfilming. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help you understand markings or notations which may appear on this reproduction. 1. The sign or “target” for pages apparently lacking from the document photographed is "Missing Page(s)”. If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure you of complete continuity. 2. When an image on the film is obliterated with a round black mark it is an indication that the film inspector noticed either blurred copy because of movement during exposure, or duplicate copy. Unless we meant to delete copyrighted materials that should not have been filmed, you will find a good image of the page in the adjacent frame. If copyrighted materials were deleted you will find a target note listing the pages in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photo­ graphed the photographer has followed a definite method in “sectioning” the material. It is customary to begin filming at the upper left hand corner of a large sheet and to continue from left to right in equal sections with small overlaps. If necessary, sectioning is continued again—beginning below the first row and continuing on until complete.

Prehistoric organic and lithic hunting artifacts and fauna had melted from the ice patches and were subsequently recovered. These items include arrow shafts, barbed antler points, lithic projectile points, and what is likely a stick for setting ground squirrel snares. Or- ganic artifacts recovered from this survey date within the last thousand years. Lithic projectile points recovered from ice patches suggest that prehistoric hunters have been hunting caribou on ice patches in the Denali Highway region for at least the last half of the Holocene. keywords: atlatl, bow and arrow, gopher stick, mountain archaeology INTRODUCTION Ice patches with caribou (Rangifer tarandus) dung and cul- al. 2005; Hare et al. 2004a, Hare et al. 2004b).

  • Routes to Riches 2015 1 Danielhenryalaska.Com
    Routes to Riches 2015 1 danielhenryalaska.com Routes to Riches Daniel Lee Henry [email protected] A ground squirrel robe nearly smothered northern Tlingits’ nascent trust in their newly-landed missionaries. Long-time trading ties with Southern Tutchone and Interior Tlingit funneled wealth to Native residents of the upper Lynn Canal. Luxurious furs from the frigid north brought prices many times that of local pelts. For example, while the coastal red fox fur was worth $1.75 in “San Francisco dollars” in 1883, a Yukon silver fox brought up to $50 (about $1200 in 2015). Several times a year, Tlingit expeditions traversed routes considered secret until local leaders revealed their existence to Russians and Americans in the mid-nineteenth century. A day’s paddle to the upper Chilkat River brought travelers to a trail leading over through barrier coastal mountains into the vast, rolling subarctic Interior. On the eastern route, packers left Dyea at the terminus of Taiya Inlet and slogged a twenty-mile trail to a keyhole pass into lake country that drains into the Yukon River headwaters. The image of prospectors struggling up the “Golden Staircase” to Chilkoot Pass engraved the Klondike gold rush of ‘98 onto the license plates of cultural memory. For centuries, Chilkats and Chilkoots sustained a trading cartel connected by their respective routes. From tide’s edge to the banks of the Yukon River four hundred miles north, Tlingits insisted on customer allegiance. They discouraged Interior trading partners from commerce with anyone but themselves and expressly prohibited economic activity without invitation. The 1852 siege of Fort Selkirk and subsequent expulsion of Hudson’s Bay Company demonstrated the market realities of the Chilkat/Chilkoot cartel.

  • Monarch Mountain/A Xéegi Deiyi Conservancy
    Monarch Mountain/A Xéegi Deiyi Conservancy Management Plan February 2016 Cover artwork: Wayne Carlick Foreword Tlingit Elders teach their people to work respectfully with all those who come to Taku River Tlingit traditional territory, to find ways to work together with respect and harmony. This conservancy management plan is part of the on-going collaboration between the Taku River Tlingit First Nation and the Province of British Columbia to sustainably manage the lands and resources of Tlingit territory through mutual respect and understanding. Wóoshtin wudidaa (the Atlin Taku Land Use Plan) set the stage for the Tlingit vision for a connected network of protected areas to be realized. These protected areas were identified to: protect important Tlingit cultural sites and landscapes; ensure continuation of Tlingit khustiyxh (way of life); sustain biological diversity and important wildlife habitats; and protect landscapes and places of importance for recreation and tourism. The Monarch Mountain/A Xéegi Deiyi Conservancy is an important part of Tlingit Tlatsini – the network of “places that make us strong.” We invite you to read and understand the importance of this place to the Tlingit people, and to others who make this region their home. We also invite you to explore and enjoy Monarch Mountain/A Xéegi Deiyi Conservancy, and take part in conserving and protecting its resources for future generations.
