Land holdings in most of southern Manitoba have been determined using one of two systems. The older long-lot system, derived from the St. Lawrence lowlands in Quebec, is found along the Red River, along the Assiniboine River west to Portage la Prairie, as well as in several other isolated areas. Lots were laid out at right angles to the river, resulting in a distinctive pattern easily observed on remotely sensed images. The DSL system, which divided land into one square mile sections, was applied to virtually all other areas. The resulting squared pattern is a prominent feature on remotely sensed images. Interesting situations occur where the two systems come into contact. The DLS system was amended several times, but in Manitoba there is evidence of only the first and third systems. Careful interpretation of air photos can reveal the differences between the two systems.
This area is located in ranges 12, 13 and 14 WI in the Interlake where much of the land is agriculturally marginal. A lot of woodland 1, scrub 2, marshland 3, and a partially dried up lake 4—Pockett Lake—can be seen. Few of the road allowances are used for gravel roads, making it difficult to identify the correction line. However, by tracing the township line between townships 18 and 19 5 west from the eastern edge of the photo, it can be seen that the north/south section lines do not coincide north and south of the township line; this is because of the correction which here is about 0.3 miles (0.5 km) 6.
This area has been recently—geologically speaking—uncovered by the eastward retreat of Lake Manitoba, leaving a general north-northwest/south-southeast alignment of landforms. Linear features of note are the CN line 7 from Glenella 8 (which, however, has a road system aligned with the DLS system) through Glencairn 9 to McCreary, which is off the photo to the northwest. Roughly parallel is a drainage ditch 10 that empties into Big Grass River 11 in the southeast. PR 261 12 runs east/west across the south.
