Dry Mixedwood Subregion
)
The Dry Mixedwood Subregion is characterized by low relief and level to undulating terrain. Surficial materials are mostly till as ground
moraine and hummocky moraine landforms with some areas of
Aeolian dunes and sandy outwash plain. The Subregion includes two main areas: the southern edge of the
Boreal Forest Natural Region from Cold Lake west to about Barrhead and south along the western edge of the
Central Parkland Subregion to about Gull Lake and a broad
strip of land from Lesser Slave Lake to Grande Prairie then north along the Peace River to Fort Vermilion. The Cooking Lake moraine east of Edmonton is a disjunct portion of this Subregion.
Drainage is to both the Saskatchewan and Mackenzie River systems via numerous rivers and small streams.
