The Northern Fescue Subregion
)
Topographically, the Northern Fescue Subregion is characterized by gently rolling terrain. The most common landforms are
hummocky and low-relief ground moraine. Areas of outwash and sand plains, dune fields, and fine-textured
glaciolacustrine deposits occupy a smaller,
yet significant, amount of the landscape. Eroded plains are important in the Sullivan Lake
area and the lowest elevations are in the eastern parts of the Subregion.
Stream drainage is part of the Saskatchewan River system except for a large area of internal drainage in the Sounding Creek basin. Few stream valleys dissect the subregion but those with permanent flow are usually well-incised.
