The
Parks / Yukon
Territory / Vuntut
National Park

|
The southern third of the park
is part of the Old Crow Flats, a unique landscape
of more than 2000 shallow lakes, ponds and meandering
rivers underlain with permafrost that extends
from a few inches below the surface of the ground
to depths of over 300 meters. Unable to drain
away, meltwater accumulates in a watermaze of
bogs and streams. Nearly surrounded by mountains,
which rise as high as 1500 metres, the basins
lakes, even at the low elevation of 300 metres,
are well above the highest spring flooding.
Abundant shallow water, 24 hour sunlight and
warm summer temperatures make the lakes exceptionally
productive for this latitude: the vegetation
consists of wetland and aquatic species, moist
tundra, cottongrass meadows and open stands
of stunted white or black spruce. In the northern
two thirds of the park are the old, gently-rising
hills called pediments surrounding the upper
Old Crow Basin and farther north and west, the
foothills of the British Mountains are cloaked
in sedge tussocks, shrubs and open stands of
spruce - the northern limit of trees in Canada.
