Description

This article summarizes geochemical and mineralogical analyses of the material called Glacier Pass Concretions including portable X-ray fluorescence, thin sections, and hyperspectral imaging. Results indicate that pre-contact toolmakers were aware of internal inconsistencies in concretions and targeted specific high silica bands that produced a better quality, predictable substrate for tools. The article presents photographic libraries to aid identification and summarize an archaeometry-based reconstruction of pre-contact cognitive approaches to a raw material seasonally exploited in an alpine area for several thousand years.

Ecological sites of the Subalpine subregion. Second approximation

The Subalpine Natural Subregion is a Rocky Mountain altitudinal vegetation zone extending from an elevation of 1575 m to 2175 m at its southernmost occurrence and 1365 m to 2000 m near Grande... More ≫

Description

The Subalpine Natural Subregion is a Rocky Mountain altitudinal vegetation zone extending from an elevation of 1575 m to 2175 m at its southernmost occurrence and 1365 m to 2000 m near Grande Cache. This approximation of the guide represents the analysis of over 3400 plots described in the Subalpine subregion. In this subregion it was found there were distinct differences between the community types and ecological sites between the Central and Northern Foothills and Mountains (west of Sundre, Hinton, Grande Cache and Jasper national park), and the Southern Rocky Mountains (south and west of Calgary and Banff national park). As a result the Subalpine plant communities are identified into two ecosections (south and north). The dominant plant species, canopy cover, environmental conditions and response to grazing, are outlined for each plant community type for each ecosection.

Description

This archaeology paper describes work at a stratified site in Jasper National Park, Alberta. Aeolian silts covering the terrace at this site (243R) contained evidence of five cultural components. Radiocarbon dates and recovered projectile points suggest that occupations occurred during the Early, Middle, and Late Precontact Periods. The preliminary results from site 243R excavations provide the basis for a much-needed occupational sequence for Jasper National Park.
