Kahboo soil series
Typical profile of a Kahboo gravelly fine sandy loam. (Soil Survey of San Juan County, Washington; by Michael Regan, Natural Resources Conservation Service)
The Kahboo series consists of shallow, well drained soils formed in colluvium from glacial drift, metasedimentary bedrock, and volcanic ash. Kahboo soils are on slopes and summits of hills and mountains. Slope ranges from 5 to 100 percent. Average annual precipitation is about 1,015 millimeters and the average annual air temperature is about 8 degrees C.
TAXONOMIC CLASS: Loamy, isotic, mesic Lithic Dystroxerepts
Average annual soil temperature - 8 to 9 degrees C.
Soil moisture control section - dry 45 to 60 days following summer solstice
Depth to lithic contact - 25 to 50 cm
Reaction - strongly acid to moderately acid
Particle-size control section:
Clay content - 5 to 15 percent
Rock fragments - 0 to 35 percent
USE AND VEGETATION: Used for recreation, wildlife habitat, homesites, and watershed. Potential natural vegetation consists of western hemlock, Douglas-fir, western redcedar, Cascade Oregongrape, prickly currant, false Solomons-seal, swordfern, and bracken fern.
DISTRIBUTION AND EXTENT: Northwest Washington; MLRA A2, Northern Part. Series is of small extent.
