Chesuncook soil series
Coarse-loamy, isotic, frigid Aquic Haplorthods
Spodosols — acid soils with a subsoil of humus and iron or aluminum
Chesuncook is mapped on 603,636 acres in 2 states, 424th nationally by area. It was established in 1992, later than all but one of the series here. Practically all of it, over 99% of its acres, lies in Maine. Besides it, only Kalkaska, Marlow, and Tunbridge have isotic mineralogy in this atlas. It is the state soil of Maine.
