Soils: Soils here raspberry moss wood ferns are of two basic types. "Regosolic soils" (poorly developed soils only recently deposited) occur along the eastern and western margins of this subregion. Everywhere else, "humo ferric podzols" are most common. These are brown soils containing mostly inorganic material and occurring in relatively dry sites. They are typically found in coniferous and mixed (both deciduous and coniferous) forests.

Geology: Rocks in this subregion belong to the Dunnage zone. To the south and north, and along the western margins of the subregion, are sandstones, shales, conglomerates, volcanic ash and lava formed about 550 million years ago. The remainder of the subregion is mostly , gabbro, and diabase intrusions that formed 450 to 550 million years ago.
