Where slopes aren't limiting, silty surficial textures result i nmoderate limitations for recreational uses and potential frost heaving results i nmoderate to severe limitations for building foundations and roads .OG 2 Map Unit (Orthic Humo-Ferric Podzols )This map unit is characterized by soils that have a silty surficial deposi toverlying a compact medium textured horizon . Otherwise they are similar to thos eof map unit OG 1 . This surficial deposit has a lower bulk density, less coarse fragments ,a finer structure, and is more friable than the underlying till, which makes these soil squite susceptible to erosion if the vegetation is removed or the soil is disturbed . Thi smap unit occurs mainly in the Amiskwi valley .
