Luvisols and Brunisols on well<br />
to imperfectly drained and<br />
Cryic Gleysols on poorly<br />
drained mineral deposits .<br />
Alpine Brunisols, slightly<br />
affected by cryoturbation,<br />
above the timberline . Cryic<br />
Fibrisols on peatlands .<br />
Lower elevations are dominated<br />
by black spruce forests . Aspen<br />
and lodgepole pine are common<br />
on burned areas . White spruce<br />
found in valleys, on better<br />
drained soils . Alpine fir forms<br />
the timberline at 3,600 feet<br />
a .s .l .<br />
Discontinuous permafrost on poorly drained finetextured<br />
soils . In alpine areas active cryoturbation<br />
was noted in association with nonsorted<br />
circles . Widespread permafrost on peatland,<br />
especially on bogs, in the form of peat plateaus<br />
and palsas .<br />
6S<br />
Luvisols and Brunisols on well<br />
to imperfectly drained<br />
deposits, except on recent<br />
alluvium where Regosols<br />
occur . Gleysols on poorly<br />
drained mineral deposits .<br />
A large portion of these<br />
Gleysols are perennially<br />
frozen . Cryic Fibrisols<br />
and Cryic Mesisols are<br />
associated with bogs and<br />
Mesisols are associated<br />
with fens .<br />
Good white spruce and balsam<br />
poplar on floodplains and<br />
valleys . Aspen and pine on well<br />
to imperfectly drained till and<br />
sands . Dense black sprucefeathermoss-Ledum<br />
type of vegetation<br />
on peatlands and poorly<br />
drained mineral soils .<br />
Discontinuous permafrost on peatlands and<br />
poorly drained mineral soils . On peatlands,<br />
peat plateaus and palsas are the permafrost<br />
landforms .<br />
6N<br />
Brunisols on well to imperfectly<br />
drained mineral<br />
deposits, except on recent<br />
alluvium where Regosols<br />
occur . Cryic Gleysols on<br />
poorly drained mineral<br />
deposits and Cryic Fibrisols<br />
on peatlands .<br />
White spruce and balsam poplar on<br />
floodplains and valleys . Aspen<br />
and jack pine on well to imperfectly<br />
drained tills, sandy and<br />
gravelly deposits . Somewhat<br />
open black spruce-lichen-Ledum<br />
type of vegetation on peatlands<br />
and poorly drained mineral soils .<br />
Widespread permafrost on peatlands and poorly<br />
drained mineral soils . On peatlands, peat<br />
plateaus and palsas are the permafrost landforms<br />
.
