MLRA 55A - Northern Black Glaciated Plains North Dakota 32,240 km2 (12,450 mi2)

Soils:
Most of the soils are Borolls and Aquolls. They are deep, well drained to poorly drained, and sandy, loamy, and clayey and have a frigid temperature regime and mixed mineralogy. The nearly level and undulating Haploborolls (Barnes, Svea, Gardena, and Hecla series) are on till plains and glacial lake plains. Very poorly drained Argiaquolls (Parnell series) and Argialbolls (Tonka series) are in kettle holes. The sloping to steep Haploborolls (Buse series) are on till plains. Argiborolls (Bottineau and Kelvin series) are on till plains in the forested areas.
