“…A third B horizon observed was labeled a Bw horizon because it did not meet the requirements for spodic materials. Most Histosols are located in low-lying wetlands, but a small subset in the Northeast are found on cold mountain summits and upper sideslopes, such as the Mount Mansfield Forehead plot (Villars, 1996;Soil Survey Staff, 1998a;Bockheim, 2010). These Histosols have organic soil materials that "constitute two-thirds or more of the total thickness of the soil to a densic, lithic, or paralithic contact and have no mineral horizons or have mineral horizons with a total thickness of 10 cm or less" (Soil Survey Staff, 2014, p. 38, key to soil orders B2c).…”

“…The https://soilseries.sc.egov.usda.gov/OSD_Docs/L/LONDONDERRY.html series classification is loamy, mixed, active, acid Lithic Cryorthents; the https://soilseries.sc.egov.usda.gov/OSD_Docs/S/STRATTON.html series classification is loamy‐skeletal, isotic Lithic Humicryods. Bockheim (2010) described these high‐elevation northeastern US soils as “disjunct” soils, which have formed on “widely separated mountain peaks over a broad geographic region.”…”

As part of the Vermont Long‐Term Soil Monitoring Project, five 50 × 50 m plots were established on protected forestland across Vermont. In 2002, ten randomly selected subplots at each monitoring plot were sampled. The 10 pedons sampled at the high‐elevation spruce–fir “Forehead” plot on Mount Mansfield were found to include soils of four taxonomic Orders: Entisols, Histosols, Inceptisols, and Spodosols. Soil forming factors such as climate, vegetation, and time are uniform, and podzolization is the major soil forming process, but small variations in parent material thickness and microtopography result in the presence of four orders. A 1‐cm difference in the thickness of a horizon can affect the placement of a soil in one of these orders.

“…Gleby górskie, przynajmniej na czêci obszarów górskich, posiadaj¹ cechy morfologiczne i w³aciwoci fizykochemiczne, które odró¿niaj¹ je od ich nizinnych analogów oraz decyduj¹ o u¿ytecznoci, produktywnoci lub funkcjach rodowiskowych [Adamczyk 1984]. Niektóre gleby, powsta³e w wyniku dzia³ania lokalnego zespo³u czynników rodowiskowych, wystêpuj¹ tylko na niektórych obszarach górskich, podobnie jak endemity w wiecie rolin i zwierz¹t [Bockheim 2010;Komornicki, Skiba 1996]. W przesz³oci skutkowa³o to odrêbnym traktowaniem gleb górskich i nizinnych w klasyfikacjach lub na mapach glebowych [PTG 1956].…”
