EUB/AGS Map 314
Surficial Geology of the Sawn Lake Area, Alberta (NTS 84B/13)
Background
As part of a four-year, collaborative, multidisciplinary project initiated in 2003 under the Geological Survey of Canada’s Northern Resource Development Program (NRD Project 4450), the Geological Survey of Canada (Natural Resources Canada), Alberta Geological Survey (AGS) and Resource Development and Geoscience Branch (British Columbia Ministry of Energy, Mines and Petroleum Resources) have undertaken extensive Quaternary geology studies in northwestern Alberta and northeastern British Columbia.
To support the kimberlitic research subproject, detailed surficial mapping at 1:50 000 scale was conducted in the Sawn Lake map area (NTS 84B/13), where the majority of the kimberlites in the Buffalo Head Hills field are located. This mapping initiative was also undertaken as part of an undergraduate thesis project (Trommelen, 2004). Fieldwork was conducted during August 2003. Particular attention was paid to surface stratigraphy, ice flow indicators and the highly variable nature of the surface sediments. These observations augment existing surficial geology information available for this region (Paulen et al., 2003). Additional information and descriptions on the surficial geology of this region are available from Paulen et al. (2006) and Trommelen and Paulen (Surficial geology of the Sawn Lake Region, Alberta, NTS 84B/13, work in progress, 2006). A model for the Late Wisconsin ice flow history is presented in Paulen and McClenaghan (in press).
Surficial Map
Initial preliminary maps were compiled using 1:20 000 and 1:40 000-scale air photographs, supplemented by LandSat 7 satellite and Shuttle RADAR Topography Mission (SRTM) DEM imagery. After field checking, the revised surficial maps were scanned and vectorized using ArcInfo™. Following review and editing, the final map products were prepared.
Navigation of Files
This compact disc constitutes release of AGS Map 314 prepared for the Alberta Energy and Utilities Board/Alberta Geological Survey (EUB/AGS) by M. Trommelen, R.C. Paulen and J. Weiss. The intent is to make this map available in common digital formats to meet the needs of two groups of users: GIS operators and those requiring an exact version of the published map in a readily printable format. GIS files are available in ArcInfo Export (.e00) and shapefile formats. The printer-ready files are in Adobe's Portable Document Format (PDF).

Shapefiles provided were created in ArcView version 3.2a. Metadata for each shapefile are contained in *.txt, *.html and *.xml files.
Acknowledgements
Surficial mapping was completed in 2003 as an AGS contribution to NRD Project 4450 and the Quaternary mapping initiative under the Alberta Mineral Strategy. Observations and data collected by previous AGS research activities were made available to augment field observations. For this we are indebted to Roy Eccles, Mark Fenton, John Pawlowicz and Glen Prior. Digital cartography and GIS was completed at the AGS by Monica Price and Natasha Clarke. Mark Fenton and Glen Prior are thanked for providing constructive comments which helped improve this map.
