Chapter 3: Geologic Structure and Landforms

3.69: The Arden Ridge East of Birnie

Some of the Lake Agassiz strandlines are so prominent that they have been given names. One such is the Campbell Beach, a prominent ridge which stands as much as 10 metres (32.8 feet) above the surrounding land. In the area shown here the Campbell Beach is referred to as the Arden Ridge because it runs through the small settlement of Arden located 7 miles (11 km) south of the photo. A gravel road, PR 352 1 between Arden and Birnie follows the ridge on the east side of the photo. Its direction contrasts sharply with the normal north/south and east/west trending roads in the area. Other strandlines to the east 2 are at a lower elevation and are more recent, whereas strandlines in the west 3 are higher and older. The CN line 4 near Birnie 5 follows the strandline direction in the north before veering off to the west in the south.

Drainage in the area is generally from the higher land in the west to lower land in the east. Several small creeks can be seen 6, one of which is deflected south by the Arden Ridge 7. However, Birnie Creek 8 in the north flows across the strandlines without interruption, but in the northeast it has been straightened 9 to improve its flow rate. One small creek has been dammed to create a reservoir 10 for water supply at a neighbouring farm. Land between the two sets of strandlines is dry; consequently, much of it has been left with a scrub cover 11. In order to improve water supply—mainly for use by cattle—numerous dugouts (small black rectangles on the photo) have been excavated 12.

As is usually the case with photos of southern Manitoba, section lines 13 and quarter-section lines 14 can be seen. Section lines are marked by a road allowance of 99 feet often not used in this area 15, whereas quarter-section lines are usually picked out by land use variations 16. The fifth baseline of the DLS between townships 16 and 17 runs across this area 17.
