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 glacio-fluvial parent material. There is a dark-coloured Ap horizon that is > 10 cm thick.
