Overview
In the mid-latitude mountains of North America, archaeological materials have been identified in association with kinetically stable \"ice patches\" that attracted animals and their human predators. The stable ice in these features exhibits little internal deformation or movement and can preserve otherwise perishable materials for millennia. Eight prehistoric sites have been identified in association with perennial ice patches within the Greater Yellowstone Area of Montana and Wyoming. Surveys in Colorado have produced paleobiological samples, but no definitive archaeological sites. Archaeological remains include ancient wooden dart shafts and fragments, wooden artifacts of unknown function, a wrapped leather object of unknown function, butchered animal remains, and chipped stone artifacts. Fragments of weapons ranging in age from 200 to 10400 years suggest long-term continuity in ice patch hunting in the region. Paleobiological specimens range in age from several hundred to nearly 8000 years. Bighorn sheep (Ovis canadensis) is a presumed prey species, but the remains of bison (Bison bison) and other large ungulates also occur. Ice patches offer important insights into the use of high-elevation environments by Native Americans. Efforts are ongoing to build and maintain awareness of these resources among federal land managers and the public. Dans les montagnes de latitude moyenne de l'Amérique du Nord, du matériel archéologique a été repéré dans des « névés » cinétiquement stables où évoluaient certains animaux de même que leurs prédateurs humains. La glace stable de ces névés présente une déformation ou un mouvement interne minime, ce qui permet de préserver des matériaux périssables pendant des milliers d'années. Huit sites préhistoriques ont été répertoriés dans les névés pérennes de la grande région du Yellowstone se trouvant au Montana et au Wyoming. Au Colorado, des levés ont permis de prélever des échantillons paléobiologiques, mais aucun site archéologique définitif. Parmi les restes archéologiques retrouvés, notons d'anciennes tiges et d'anciens fragments de propulseurs en bois, des artefacts en bois dont la fonction est inconnue, un objet enveloppé en cuir dont la fonction est inconnue, des restes d'animaux dépecés et des artefacts en pierre taillée. Des fragments d'armes âgés de 200 à 10400 ans laissent entrevoir que la chasse a été pratiquée dans les névés de la région pendant très longtemps. L'âge des spécimens paléobiologiques varie de plusieurs centaines d'années à près de 8 000 ans. Le mouflon d'Amérique (Ovis canadensis) y est une espèce-proie présumée, et des restes de bisons (Bison bison) et d'autres grands ongulés s'y trouvent également. Les névés permettent de mieux comprendre comment les Autochtones utilisaient les milieux en haute altitude. Les responsables fédéraux de la gestion des terres et le public déploient des efforts constants pour sensibiliser les gens à ces ressources.
