The Foothills Parkland Subregion occupies a narrow band along eastern edge of the geological foothills from Calgary south to the Porcupine Hills, and from Pincher Creek south to the
American border in the Waterton Lakes National Park area. The topography is rougher than that of the
Central Parkland Subregion, and elevations are higher, ranging to over 1300 metres
near Paine Lake. There are also a number of permanent streams that drain into the Saskatchewan River system.
Surficial deposits include extensive areas of hummocky and ground
moraine as well as more restricted areas of outwash and
glaciolacustrine deposits along valleys. Extensive river terraces also occur in some areas.
