The Subalpine Subregion

Subalpine Region LandscapeThe Subalpine Subregion occupies a band between the Montane and Alpine Subregions in the south and between the Upper Foothills and Alpine Subregions in the north. The boundary between the Subalpine and the Upper Foothills is based partly on the changes from Foothills bedrock to Rocky Mountain strata, although portions of the Foothills Geological Belt are included in the Subalpine Subregion in the Kakwa area.

The upper limit of the Subalpine Subregion ranges from about 2300 metres in southern Alberta to 2000 metres in northern Alberta. Lower elevational limits are around 1600 metres in the south and 1350 metres in the north. Morainal materials occupy much of the Subalpine Subregion with colluvial and residual bedrock materials frequent at higher elevations. Fluvial and glaciofluvial deposits are common along stream valleys, with lesser amounts of glaciolacustrine and aeolian materials.
