Lithic Orthic Re gosol<br />
These soils have an organic-rich mineral horizon (Ah) .<br />
The<br />
lithic contact occurs at a depth greater than 10 cm but less than 50<br />
cm<br />
below the mineral surface .<br />
These soils-have developed on colluvial<br />
materials of the Mackenzie and Franklin Mountains . A representative<br />
profile of Lithic Orthic Regosol, sampled on Ram Plateau, is described<br />
below :<br />

Lithic Orthic Regosol (Appendix I : Table 23)<br />
L-H-<br />
7 to 0 cm, black (l0YR 2/1, moist), litter of ericaceous<br />
shrubs, lichens, mosses and grasses ; slightly acid ; clear,<br />
wavy boundary .<br />
0 to 15 cm, very dark gray (l0YR 3/1, moist), silt loam ;<br />
fine granular ; non-sticky, non-plastic ; very friable<br />

Lithic Orthic Regosol*<br />
These Lithic Orthic Regosols affected by cryoturbation are found<br />
on non-sorted circles and stone stripes . The surface of the soil<br />
is covered with various amounts of unsorted stones and intrusions of<br />
organic materials are common throughout the profile . A representative<br />
profile of a cryoturbed Lithic Orthic Regosol, sampled on a nonsorted<br />
circle, is described below :<br />
