Description
The DLS System (Third System) East of Duck Mountain Southwest of Ethelbert

This small-scale photo shows a mainly agricultural area 1 east of Duck Mountain that is mainly wooded and therefore dark-toned 2. Traversing the area from north-northwest to south-southeast are several Lake Agassiz strandlines 3 identified on the basis of tonal variations that reflect different land uses. Another group of strandlines 4 at a lower level can be seen in the northeast.

North of township 27, the Third System of the DLS is used. Under this new system, adopted in 1881, townships were 6 chains shorter measured north/south and 3 chains narrower measured east/west (along the base lines). Road allowances were reduced in width to 1 chain (66 feet) compared with 99 feet in the First System. Road allowances run north/south between all sections; but east/west road allowances occur every two sections. Most of these changes are not visible on air photos, but the existence of east/west road allowances every two sections is obvious, as light-toned gravel roads have been constructed along most of them 5 as indicated on the overlay. Quarter sections can be identified in agricultural areas as they are often marked by dark-toned hedges 6, whereas in wooded areas they are light-toned clearings 7.

PTH 10 8 in the east follows the trend of one of the Lake Agassiz ridges, departing from the usual north/south or east/west arrangement of roads. The CN railway line 9 clips the northeastern corner of the area, and an intermittent light-toned line 10 indicates the location of a power line.
