Description

Microblade technology in western Canada is reviewed within a regional framework to broaden archaeologists’ understanding of its geographic and temporal distribution. Substantial references are made to archaeological grey literature. Focusing on two main microcore forms (Denali and fixed platform), the technology is shown to be found throughout the Holocene epoch, concentrated principally in British Columbia and the Yukon, with fewer occurrences in the Northwest Territories and Alberta. Microcore morphologies are strongly dependent on the qualities of toolstones used in their manufacture; the principal core forms demonstrate regionally distinct distributions and weak temporal trends. From the Late Pleistocene and through the Holocene, microblade technology in northwestern North America appears to increase and decrease in popularity on track with major climatic episodes. Substantial progress has been made in recent times in substantiating a north to south time-slope trend in...

Description

This paper describes a surface collection from the Gull Lake site near Fort Vermilion in northern Alberta. The site yielded an assortment of tools, including a complete microblade core, several diagnostic projectile points made from a variety of lithic raw materials (including one specimen resembling Angostura Paleoindian points). We hypothesize that the Gull Lake site represents one of several areas in the northern Alberta Boreal Borest that were prairies purposely maintained by First Nations peoples to attract large game animals such as woodland bison. Once these and other large animals were depleted after contact, First Nations peoples no longer used the site in favor of other still productive game animal areas in northern Alberta.

Description

Contrary to the prevailing belief that microblade production was a complicated process that involved indirect percussion or assisted pressure and holding devices, a simple free-hand pressure technique can easily replicate examples comparable to those recovered from pre-contact sites. This paper argues that such a technique prevailed in the past, and that many of the variations in formal and metric attributes of archaeological microblade cores and microblades are the result of a wide range of environmental, behavioural, and functional variables rather than of completely different methods of manufacture.
