The primary objectives of the post-impact assessment were to: inventory historical resource sites within the development zone; evaluate the significance of the individual sites identified; assess the nature and magnitude of site-specific impacts; and design and implement an acceptable site-specific mitigation program which would significantly eliminate potential future impacts to identified sites. A record review was conducted to identify previously recorded sites that could be affected by the development project, and to determine the nature of the database in the area. Ground reconnaissance was done to relocate, previously recorded historical resource sites as well as to identify and record any new sites within the development zone. Site discovery and post-impact assessment include the visual examination of post-clearing surfaces within the right-of-way, inspection of adjacent exposures, supplemented by shovel testing in areas of identified cultural material or potential site areas lacking suitable exposures. The reconnaissance serves to complement the fieldwork carried out during the initial, pre-construction assessment; site evaluation to evaluate the nature of the existing resource database, the quantity and quality of observable remains (e.g. site condition, content, uniqueness, and complexity) and the potential of the site to contribute to public enjoyment and education.. The areas targeted for this Historical Resources Post-Impact Assessment were portions of the Dover-Muskeg River 240 kV Transmission Project, located in north-eastern Alberta (Figure 1). The overall length of the assessed right-of-way is 62 kilometres.
