To the south is the
Boreal Cordillera, to the east are the
Taiga Plains, and its northern extent is defined by Yukon's coastline, at which it abuts the
Southern Arctic ecozone. The northernmost area is an arctic
tundra which is beyond the
tree line, so is characterised by small
plants and
shrubs. These transition to
alpine tundra and
lowland taiga in a southeastern arc across the zone. To the northwest are rolling hills, throughout which are found broad wetlands reaching the coast of the
Beaufort Sea. The interior, comprising the
Selwyn Mountains and
Mackenzie Mountains, is primarily steep, mountainous terrain with sharp, narrow
valleys. •
