Description of soil MBSIB~~~~~N (Sinclair Bay)

Orthic Gray Luvisol

The soil is in native condition (undisturbed by agriculture).

The soil material is primarily composed of mineral particles.

The water table is not present in the soil at any time.

The growth of plant roots is restricted by the sixth layer.

Lithic (consolidated bedrock)

Water is removed from the soil somewhat slowly in relation to supply. Excess water is removed somewhat slowly due to low perviousness, shallow water table, lack of gradient, or some combination of these. Soils have intermediate to high water storage capacity (5-6 cm) within the control section and are usually medium to fined textured. Precipitation is the dominant water source in medium to fine textured soils; precipitation and significant additions by subsurface flow are necessary in coarse textured soils.

Used where there is evidence that the lacustrine materials were deposited in contact with glacial ice. One of the following characteristics must be present:

• kettles or an otherwise irregular surface that is neither simply the result of normal settling and compaction in silt nor the result of piping
• slump structures resulting from loss of support caused by melting of retaining ice
• presence of numerous ice-rafted stones in the lacustrine silts.
