Abstract: The drift thickness map of the Pelican River area (NTS 83P) shows the variation in thickness of unconsolidated sediment lying between the bedrock surface and the present-day land surface, and complements the regional drift thickness map of Alberta (Pawlowicz and Fenton, 1995). The thickness of the drift varies from less than 20 metres in uplands, such as the Pelican Mountains, to a little over 260 metres in the Wiau Valley in the northeast part of the map area. The thickest drift fills the paleovalleys containing the major valleys: the Wiau Valley and the Leismer Valley in the northeast, and the north-trending Amesbury Valley in the central portion of the area.

Supplemental Information:
Petrophysical logs were the primary source of information used for constructing the bedrock topography. A
suite of the common well logs (gamma, resistivity, spontaneous potential, density, neutron, sonic and
calliper) were useful in making the pick for top of bedrock; however, the gamma and resistivity logs proved
to be the most useful. The drift typically displays a lower gamma response and higher resistivity response
than the underlying bedrock. Other sources of data were water well lithologs, mineral exploration testholes
and information on outcrop locations.
Picking the bedrock surface was difficult in some areas where data were sparse. Many of the log traces were
absent from the upper part of the hole because of surface casing. The depth of surface casing set in bedrock
was used for an estimate of maximum drift thickness in places with few data. Conversely, many water wells
did not penetrate deep enough to intersect the bedrock, so only a minimum drift thickness value could be used.

Evaluation method description:
To generate the contour lines of the bedrock surface and drift thickness, data sources included oil and
gas wells, water wells and geologic sections along rivers. Data from 1590 points were used. Of these
data, 312 were oil and gas well geophysical logs with bedrock pick, 969 were oil and gas well
geophysical logs with bedrock above top of well logs, 103 were water well lithologs with bedrock pick,
194 were water well lithologs with depth of bedrock lying below bottom of well, 9 were cross-sections
with bedrock outcropping and 3 were cross-sections without bedrock outcrop.

Description:
The drift thickness and structure contour of the bedrock surface maps were determined from bedrock
stratigraphic picks made from three main sources: oil and gas wells, water wells and outcrops. In
oil and gas wells, the bedrock picks were made using geophysical logs. From water wells and outcrop,
lithologic decriptions were used to determine the depth to bedrock pick. Picks data were tabulated
and imported into a contour mapping software (MacCad v6.0) using a Macintosh desktop computer. The
data were then gridded by triangulation using the Delaunay tuple method. The resultant grid was then
contoured using the mapping software. The contour lines were then manually edited on the computer
using the MacCad software. Next, the final contour lines were gridded again using 400 x 400 grid
matrix to produce infill colour rendition. The drift thickness map was finally created by
subtracting the bedrock surface grid from a grid of the ground surface topography. The resultant
grid was then contoured to create the drift thickness map.
Final map preparation was as folows: the bedrock contour and gridded data were exported from MacCad in
.dxf format and imported into ArcInfo v8.3. The attributes were deleted. The coverages were
transformed from page units to real world coordinates (RMS error +/- 20 m) and projected to UTM12
NAD83. The contour lines were smoothed, tagged with the corresponding elevation/drift thickness
values and exported to shapefiles. Map compilation was done using ArcGis v8.3.
