Williams Lake Brunisol

Soil Site Details: Williams Lake Brunisol

Soils on this site are Brunisols. Brunisolic soils are relatively young, and can be viewed as an early stage in the evolutionary sequence of soil development, starting with unweathered parent material and ending with a mature soil (e.g., Podzol). The name Brunisol originated from the French word brun meaning brown.

Technical Description
This soil is in the Brunisolic Order. Brunisols are relatively young soils that can be thought of as a transition stage between Regosols and other, more developed soils (e.g. Podzol, Luvisol). The diagnostic horizon is usually a Bm horizon > 5 cm thick, which has undergone minimal pedogenic alteration (alternatively, another B horizon could be present depending on the accumulation of clay (Btj) or amorphous Fe/Al (Bfj)). This site has glaciofluvial parent material. The soil at this site falls into the Orthic Dystric Brunisol Subgroup. This soil is further classified under the Alix soil association.PDF with details: 24_Alix.pdf
