Bedrock Topography and Drift Thickness of Peerless Lake Area, Alberta (NTS 84B)
Northern Alberta (north of latitude 55°N, or approximately Lesser Slave Lake) is covered by approximately 14 1:250 000-scale map areas that are either unmapped or inadequately mapped with respect to surficial geology, Quaternary stratigraphy, bedrock topography and drift thickness. Bedrock topography and drift thickness mapping are part of an Alberta Geological Survey multi-year initiative to complete the mapping coverage of northern Alberta at 1:250 000 scale. The maps show structure contours of the bedrock surface and thickness of drift from the ground surface to the top of the bedrock. The drift includes all of the glacial, pre-glacial and post glacial unconsolidated sediments. Data were mostly derived from oil and gas geophysical logs, with additional data from water well drillers' logs and outcrops.
This subsurface mapping initiative provides regional baseline geological information to support various private and public needs, such as the mineral and energy exploration industries, various government departments, academia, and for public use in general. These products can be a key tool for mineral and energy exploration and can aid in the prediction of overburden thickness and inferred drilling costs, provide information pertaining to the aggregate industry, aquifer delineation, and augment geophysical interpretations.
This CD contains map information from the Alberta Geological Survey for the Peerless Lake map area, NTS 84B, Alberta, Canada. Included are maps of the bedrock topography and drift thickness at 1:250 000 scale.
This compact disc constitutes release of maps 252 and 253 prepared for the Alberta Energy and Utilities Board/Alberta Geological Survey (EUB/AGS) by J.G. Pawlowicz and M.M. Fenton. The intent is to make the maps available in a variety of common digital formats to meet the needs of two user groups: 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).
A brief description follows of each of the formats and how they may be used.
Adobe® Acrobat PDF documents of the published version of the maps allows viewing on any computer capable of running a suitable version of Adobe® Acrobat Reader®.
A freeware version of Adobe® Acrobat Reader® for Microsoft® Windows® is included on the CD-ROM. Adobe® Acrobat Reader® for other platforms are available from Adobe's Web site at http://www.adobe.com/.
To install the software, double-click the "acrobat.exe" file and follow the instructions for installation.
