Bedrock Topography and Drift Thickness of Zama Lake Area, Alberta (NTS 84L)
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 the general public. 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 Zama Lake map area, NTS 84L, Alberta, Canada, included are maps of the bedrock topography and drift thickness at 1:250 000 scale and a data file of depth to bedrock picks used in producing the maps.
This compact disc constitutes release of maps 328 and 329 prepared for the Alberta Energy and Utilities Board/Alberta Geological Survey (EUB/AGS) by Pawlowicz, J.G., Hickin A.S., Nicoll, T.J., Fenton, M.M., Paulen, R.C., Plouffe, A. and Smith, I.R. 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).
Once you have installed Adobe® Acrobat Reader®, you can print and navigate to the desired section via the table of contents and the links throughout the report. The links in the table of contents are rollover links, and the 'hand' will turn to a 'pointing hand' when you move your mouse over a section. The links in the report are outlined in blue.

Also on the CD is a metadata folder. Metadata, or "data about data," describe the content, quality, condition and other characteristics of the data.
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 allow viewing on any computer capable of running a suitable version of Adobe® Acrobat Reader®.Acrobat Reader® is available from Adobe's website at http://www.adobe.com/.

A data file of bedrock stratigraphic picks is available in Microsoft Excel 2003.xls and CSV (comma delimited) formats.
The Zama Lake (NTS 84L) bedrock topography and drift thickness maps were completed as an Alberta Geological Survey and Geological Survey of Canada collaborative contribution to Northern Resources Development Project 4450, Shallow Gas and Diamond Opportunities in Northern Alberta and British Columbia 2003-2007, with funding support from the second phase of the Targeted Geoscience Initiative program. Final digital cartography/GIS by M.C. Price, data compilation assisted by T. Berezniuk and editing by G. Hippolt-Squair and G.J. Prior. Digital base map provided by Resource Information Management Branch, Strategic Corporate Services, Alberta Sustainable Development, supplied by Spatial Data Warehouse. Digital elevation model provided by Geomatics Canada, Natural Resources Canada.
