Calgary, Alberta, Canada T2P 3Tl Telephone (403) 299-5600 Fax (403) 299-5606 REPORT ON IDSTORICAL RESOURCES IMPACT ASSESSMENT FOR SUNCOR'S PROJECT MILLENNIUM. PERMIT #97-123 Submitted to: Suncor Energy Inc., Oil Sands Fort McMurray, Alberta Prepared by: Grant M. Clarke Golder Associates ltd. Calgary, Alberta October 1998 972-2205 OFFICES IN AUSTRALIA CANADA GERMANY, HUNGARY, ITALY, SWEDEN, UNITED KINGDOM, UNITED STATES EXECUTIVE SUMMARY In the autumn of 1997, Golder Associates Ltd. completed an Historical Resources Impact Assessment (HRIA) on behalf of Suncor Energy Inc. (Suncor). This HRIA was completed to investigate lands proposed for disturbance during construction and operation of Suncor's Project Millennium. Project Millennium is located on the south and east sides of the Steepbank Mine, north of Fort McMurray. All work completed for this Project was conducted under Historical Resources Permit #97-123, issued by Alberta Community Development to Grant Clarke. The field assessment was completed under the direction of Mr. Clarke. Field crews varied in size from three to five archaeologists and included Grant Clarke, Brian Ronaghan, Dana Dalmer, Sid Rempel and Terry Beaulieu. The Millennium Project will impact portions of four Townships of land including T91-R09, T92- R09, T91-R08 and T92-R08-W4M. Due to the fact that the project encompasses large tracts of land covered by fens and other areas exhibiting varying degrees of potential for historical resources, a vegetation and hydrology based model was used to define areas of high, moderate and low potential prior to the initiation of field work. Observations made as during the course of aerial reconnaissance and in-field inspection resulted in a modification of the original assessment of potential. Field work included concentrated pedestrian inspections of high and moderate potential areas, and aerial reconnaissance of areas of low potential. Aerial reconnaissance was also completed over the entire project area in an effort to ensure adequacy of the inspection strategy. In accordance with the distribution of high and moderate potential areas, field investigations were concentrated in two locations. The first location is situated in the southern portion of the HRIA study area, along Wood and McLean creeks. The second area is situated along the northern and eastern portions of the study area, along the top of the Steepbank River terrace. Two previously recorded prehistoric sites, HfOu 1 and 2, are located in the vicinity of the HRIA study area. These sites are both isolated find locations and were recorded during the HRIA completed for the Steep bank Mine. Neither of these sites were recommended for further study at that time and were not revisited during the course of this investigation. Site file searches also indicated that five historical sites had been recorded in the vicinity of the Project Millennium development area. These include four well locations drilled by Count Alfred Von Hammerstein (HS 44043, 44045, 44046 and 44047) and one well location drilled by the Athabaska Oil and Asphalt Company (HS 44044) in the early 1900's. Only two of the sites lie potentially within Project Millennium mine footprint. Due to scant record information, one of these locations (HS 4044) cannot be verified beyond a half section of land: the south half of Section 20-91-09-W4M. Only a small part of this half section is located within the Project Millennium footprint. Site HS 44043 is located within the mine footprint, in LSD 14-10-91-09- W4M. The remaining three sites are located within the Steepbank Mine footprint. None of these sites appear to have been field assessed during the original recording. All site information was originally obtained from published texts (Ells 1926; de Mille 1969). No physical remains were observed during the course of the Steepbank or Millennium Mine HRIAs to confirm the locations of these sites. Field assessment resulted in the observation of three cultural resources and one palaeontological locale. The cultural sites include two trappers cabins and one site of unknown origin identified by a moderate sized depression, an associated mound, and a sparse artifact scatter. As none of these sites are greater than 50 years of age they do not qualify as historical resources under the Alberta Historical Resources Act and were not formally recorded. However, these sites do help us understand the historical and traditional land use practices in the region. The palaeontological site consists of an outcrop of bedrock located along the eastern edge of the Athabasca River. The bedrock is part of the Moberly Member of the Waterways formation. The Waterways formation is Upper Devonian in age and outcrops regularly along this section of the Athabasca River. Fossils included in this outcrop include bulbous stromatoporoids, mullosc shells and other marine invertebrates. A cumulative effects assessment of the current and proposed oil sands mining operations in northeastern Alberta was also completed as part of this assessment. This analysis expands current understandings of the distribution of sites in the region and provides a possible explanation for why there is a relatively sparse concentration of historical resources throughout the Project Millennium development area.

  • A Chronological Outline for the Athabasca Lowlands and Adjacent Areas
    6 A Chronological Outline for the Athabasca Lowlands and Adjacent Areas brian o. K. rEEves, JanEt blaKEy, and Murray lobb Since the early 1970s, archaeological studies in the Athabasca lowlands and the Birch Mountains have recorded a large number of sites that contain significant numbers of stone tools, including diagnostic artifacts, among them projectile points (fig 6.1). While some of the earlier studies originated in academic research, most of them have taken place in connection with proposed oil sands development or local or regional infrastructure projects. Our intent in this chap- ter is to outline, refine, and update the cultural chronology of the Lower Athabasca region in the light of existing studies and on the basis of the provincial database of archaeological sites. PaSt chronological Studies The first generalized chronologies of the Athabasca lowlands and adjacent areas date to the mid-1970s and were based on reconnaissance surveys, test excava- tions, and detailed excavations carried out by Archaeological Survey of Alberta staff archaeologists Paul Donahue (1976), John Ives (1977), and John Pollock (1978b). The results of these studies were later summarized by Ives (1981). Detailed discussions of chronology also appeared in the Historical Resource Impact Assessment reports pertaining to two major oil sands leases, Shell’s Alsands Lease 13 (Ronaghan 1981a, 1981b) and Syncrude Lease 22 (Van Dyke and Reeves 1984). Ives (1993) subsequently provided an in-depth discussion of the doi: 10.15215/aupress/9781926836904.01 161 r ! e v i R t r R o i F c Figure 6.1. Lower Athabasca study k h ee d Cr r a l area.

  • Winter Lakekeepers 2019
    Winter LakeKeepers 2019 ALBERTA LAKE MANAGEMENT SOCIETY’S OBJECTIVES ALMS has several objectives, one of which is to collect and interpret water quality data on Alberta Lakes. Equally important is educating lake users about their aquatic environment, encouraging public involvement in lake management, and facilitating cooperation and partnerships between government, industry, the scientific community and lake users. ALMS would like to thank all who express interest in Alberta’s aquatic environments and particularly those who have participated in the LakeKeepers program. These leaders in stewardship give us hope that our water resources will not be the limiting factor in the health of our environment. ACKNOWLEDGEMENTS The LakeKeepers project was made possible with support from Alberta Ecotrust. We would like to thank the volunteers who made this program happen: Jon Pedlan, Ray Walker, Vien and Marielle Lam, Cam and Brittany Kereliuk, Kellie Nichiporik, Steve Hawryliw, and Blake Mills. We would also like to thank the Mighty Peace Watershed Alliance, the Alberta Conservation Association, and the Calling Lake Cottage Association for their assistance with coordinating volunteers and sample shipment. A special thanks to Cerina Lee for developing the LakeKeeper training videos. This report has been prepared by Caitlin Mader, Bradley Peter, Patrick Heney, and Caleb Sinn. EXECUTIVE SUMMARY In 2018, the Alberta Lake Management Society, with financial support from Alberta Ecotrust, piloted the LakeKeepers project. This project was designed to enable stewards to conduct lake monitoring by providing them with training and sampling equipment. In early 2019, this project was expanded to include winter under-ice sampling, with the cooperation of ice anglers.

In the Fall of 2018 the Athabasca Native Friendship Centre partnered with the Indigenous Tourism Association of Canada, the newly formed Alberta Indigenous Tourism Association and Alberta Culture and Tourism to explore some potential for Indigenous Tourism opportunities that exist in our region. We focused on the communities of Wabasca, Athabasca and Calling Lake to host day long workshops. Each of our partners presented information about their organization and the benefits created through Indigenous Tourism. In the afternoon participants shared some ideas they had about their community including community assets, barriers that exist and of course the potential that abounds for entrepreneurs, investors and collaborations!

  • Environmentally Significant Areas of Alberta Volume 2 Prepared By
    Environmentally Significant Areas of Alberta Volume 2 Prepared by: Sweetgrass Consultants Ltd. Calgary, AB for: Resource Data Division Alberta Environmental Protection Edmonton, Alberta March 1997 EXECUTIVE SUMMARY Large portions of native habitats have been converted to other uses. Surface mining, oil and gas exploration, forestry, agricultural, industrial and urban developments will continue to put pressure on the native species and habitats. Clearing and fragmentation of natural habitats has been cited as a major area of concern with respect to management of natural systems. While there has been much attention to managing and protecting endangered species, a consensus is emerging that only a more broad-based ecosystem and landscape approach to preserving biological diversity will prevent species from becoming endangered in the first place. Environmentally Significant Areas (ESAs) are important, useful and often sensitive features of the landscape. As an integral component of sustainable development strategies, they provide long-term benefits to our society by maintaining ecological processes and by providing useful products. The identification and management of ESAs is a valuable addition to the traditional socio-economic factors which have largely determined land use planning in the past. The first ESA study done in Alberta was in 1983 for the Calgary Regional Planning Commission region. Numerous ESA studies were subsequently conducted through the late 1980s and early 1990s. ESA studies of the Parkland, Grassland, Canadian Shield, Foothills and Boreal Forest Natural Regions are now all completed while the Rocky Mountain Natural Region has been only partially completed. Four factors regarding the physical state of the site were considered when assessing the overall level of significance of each ESA: representativeness, diversity, naturalness, and ecological integrity.
