the second case B materials were squeezed into the Ah horizon by
frost action .
These soils are associated with nonsorted circles,
stone stripes and steps in the alpine areas of the Mackenzie and
Franklin Mountains (see Plate 7A) .
Cryic - Gleyed Orthic Eutric Brunisol
These soils have the general characteristics of Cryic Orthic
Eutric Brunisols but with mottling and dull matrix colors in the
B horizons .
The Cryic Gleyed Orthic Eutric Brunisols have developed
on fine-textured till materials and are found in Zones 2 and 3
(profile B89) .
A representative profile of Cryic Gleyed Orthic
Eutric Brunisol developed on fine-textured glacial till is described
as follows :
Profile B89 Cryic Gleyed Orthic Eutric Brunisol (Fig . 11 & Appendix I : Table 17
L-H- 5 to 0 cm, dark brown (l0YR 3/3, moist), forest litter of
black spruce needles, branches, mosses and lichens ; extremely
acid ; abrupt, smooth boundary .
Bmg- 0 to 15 cm, pale brown (l0YR 6/3, moist), silty clay ;
medium granular ; slightly sticky, slightly plastic ; firm
when moist, hard when dry ; extremely acid ; clear, wavy
boundary .
Cg- 15 to 84 cm, gray (5Y 5/1, moist), silty clay loam ; weak
medium subangular blocky ; slightly sticky, slightly plastic ;
firm when moist, hard when dry ; mildly alkaline ; abrupt,
wavy boundary .
Cz- 84+ cm, frozen clay .
