tlie woody fragment content avera�es less than IS percent by volume in the control
<br /> sectian. lt is ve�y strongly acid to slightly alkaline.
<br /> The organic fayers have hue of lOYR, 7.SYR, or SYR, value oF2 to 3, and chroma a� 1 to
<br /> 3, or is in 2.5/0. The layers are predominantly muck(sapric material), but in some pedons
<br /> mucky peat(hemic material} has a cornbined thickness of less than 10 inches and pea[
<br /> (tibric material) less than S inches. Some pedons have coprogenous matecial or marly
<br /> material below S l inches

<br /> materials and concain an average of I 5 to 30 percent�voody fragments in the control
<br /> section. Lena soifs contain free carbonates throughout. Peteetneet soils are massive or
<br /> platy in bottom tier, are on elevations of about 4,500 feet, and are substantially drier in
<br /> the moisture co«trol section during the 120 days following the sumrner solstice. Saltese
<br /> and Semiahmoo soils are in areas with mild humid climates. Adrian, Linwood, Pa[ms,
<br /> and 1��illette soils have a mineral substrata depths ranging from 16 to about 50 inches.
<br /> Carbondale, Greenwood, Lupton, and Rifle soils are frigid.
<br /> GEOGRAPHIC SETTING: Houghton soi(s occupy closed depressions w'tthin lake
<br /> plains,outwash plains, ground and end moraines, and on floodplains. Slope gradients are
<br /> less than 2 percent. The mean annual precipitation ranges from about 30 to �2 inches, and
<br /> the mean annual temperature is about 48 to �3 degrees F.
<br /> GCOGRAPHICALLY ASSOCIAT�D S(3[LS: These are the \tlri:ui, Edselton(T),
<br /> I �I����rtl;, Moston(T), �iu,f;e��c�, f':�I����,, and �t ill�tt�° soils. Edselton(T) and Ed�vards soils
<br /> are underlain by marly material at depths of 16 to 51 inches. N�oston(T),and [vluskego
<br /> soils are underlain by coprogenous material between 16 and 51 inches. Poorly or veiy
<br /> poorly drained mineral soils are commonly associated along the margins of the bogs.
<br /> DRAINAG� AND PERM�ASILITY: Very poorly drained. Depth to the seasonal high
<br /> water table ranges from 2 foot above the surface in ponded phases to 1 foot below the
<br /> sin•f'ace From Sep[ember to June. The potential for s�u•face r�uioff�s very slo�v or ponded.
<br /> Permeability is moderately slo�v to moderately rapid.
<br /> USC AND V�G�TATION: A considerable area of tl�ese soils is used for cropland or
<br /> pasture. Common crops are onions, lettuce, potatoes, celery, radishes, carrots, mint, and
<br /> some corn. Native vegetation was primarily of marsh grasses, sedges, reeds, buttonbrush,
<br /> and cattails. Some�vater-tolerant trees were near tlie mac•gin of the bo�.:.
<br /> DISTRIBUTION AND �XTC1�1T: MLRA 9�, 98, l l0, t t l. Southern part of the lower
