Miscellaneous Soils
Soil Series: Armstrong (A:er), Corporation (CP),
Dub Lake (DU), Enderby (EY:er) (EY:li),
Glenemma (G:er), Iltcoola (IL), Kloag Pass (KG),
Maynard (MD), Nahun (H:er), Rutland (R:er) and
Solly (SØ)
General Characteristics: Corporation, Dub Lake,
Kloag Pass and Solly soils have developed in
sandy and gravelly coarse-textured fluvioglacial
or lacustrine deposits, Iltcoola soils in
coarse-textured sandy and gravelly fluvial
deposits and Maynard soils in medium-textured
glaciolacustrine material that is very calcareous
and weakly to moderately saline. Armstrong soil,
eroded phase, has developed in coarse-textured
glacial till deposits and have a shallow sandy
eolian surface cap. Nahun, Rutland and
Glenemma soils, eroded phases, have developed
on gravelly, cobbly, coarse to moderately-coarse
glaciofluvial deposits. Enderby soils have
developed on a stone-free, medium to moderately
fine-textured stratified glaciolacustrine
sediments. The eroded phase has a soil depth of
less than 50 cm. The lithic phase has a bedrock
contact within 75 cm of the surface. The
topography of Corporation soils ranges from
strong to extreme, 15 to 70% and Dub Lake soils
from very strongly to extreme, 30 to 70%; both
soils have a stoniness class of S0. Kloag Pass
soils have slopes that range from very gentle to
gentle, 2 to 9% and a stoniness class of S1 to S2.
Solly soils have surfaces that vary from nearly
level to gentle slopes, 0.5 to 9% and a stoniness
class of S2. Iltcoola soil surfaces vary from
nearly level to very gentle slopes, 0.5 to 9% and a
stoniness class of S0 to S4. Flooding risk is a
limitation of this soil. Maynard soils range from
gentle to extreme slopes, 5 to 70% and have a
stoniness class of S0. Armstrong, eroded phase,
slope is greater than 30% and stoniness class is S1
to S3. Nahun, Rutland and Glenemma, eroded
phases, have a stoniness class up to S4 and are
very strongly to extremely sloping (30 to 70%).
The Enderby eroded phase has slopes greater than
15% and the lithic phase has slopes that range
from 5 to 30%.
• Armstrong A:er is a poorly developed, shallow
soil found on very strongly sloping sites which
are not suited to agriculture.
• Corporation soils are severely constrained for
agricultural uses because of steep topography and
potential slope instability.
• Dub Lake soils are not suitable for agricultural
uses because of excessive slopes and instability
and erosion hazards if the thin natural vegetation
cover is disturbed.
• Enderby EY:er eroded phase, Enderby EY:li
lithic phase, these soils are generally too shallow
to support the growth of agricultural crops.
• Glenemma G:er, Nahun (H:er) and Rutland
(R:er) are poorly developed, shallow soils with a
high percent of stones or coarse fragments in
relation to the soil matrix. There is insufficient
soil to support crop production.
• Iltcoola soils are generally unsuited for
agricultural uses due to coarse, stony-textures and
the danger of flooding. Forage crops - wetter
sites may be poorly suited to some sites. These
soils have a low suitability to a narrow range of
crops, but tree fruits are being grown on some.
• Kloag Pass soils are uncommon and are not
suited to agricultural uses. No crops are
recommended on these soils.
• Maynard soils are generally not suited for
agricultural uses. Adverse topography, high
susceptibility to erosion, slow subsoil
permeability, low bearing strengths and high
salinity are all major restrictions.
• Solly soils are poorly suited for agricultural uses
and only a few areas have been developed for
pasture (forage crops - drier sites).
