this. Else where in the area they are only
a few other associations, which I might
as well describe here. The most obvious
is the "River bar" - willow zone including
the mud along the river. The mud is
dominated by Juncus, Carex aquatilis &
membranaceae, Eriophorum scheutzeri,
Deschampsia, Antiphiola and Equisetum.
The willow zone seems to be one of Salix
alpensise along the river, giving way to
S. glanca, S. richardsonii, S. ferrae, subtidally,
and finally S. bracteata inland; the whole
zone is occupied by several characteristic
flora - e.g. Hedysarum, Parnassius palustris,
Saxifraga oppositifolia, and (?Aster sibericus).
A closely related habitat is a stream
side Salix palustris association, clearly
dominated by this species and Carex
aquatilis; Hippurus & often Potentilla palustris
are common in the streams, + other aquatics.
Related to this loosely are late snowbed
valley and river bluff slopes,
with a diversified flora dominated by
frost-bushes, and characterized by such
species as Theroform richardsonii, Saxifraga
vivularis, Hydrice secotiniae, and (locally)
Ranunculus pygmaeus. The larger deep lake
