Sasquatch soil series
A representative soil profile of a Sasquatch soil. These soils form in colluvium and residuum derived from sandstone and mudstone. The thick, dark surface is the dominant feature of soils that form under a thick cover of swordfern. (Soil Survey of Redwood National and State Parks, California; by Joseph P. Seney and Alaina C. Frazier, Natural Resources Conservation Service, and James H. Popenoe, Department of the Interior, National Park Service, Retired)
The Sasquatch series consists of very deep, well drained soils that formed in colluvium and residuum derived from sandstone and mudstone. Sasquatch soils are on mountains and hills and have slopes of 5 to 75 percent. The mean annual precipitation is approximately 2030 millimeters (80 inches) and the mean annual temperature is approximately 11 degrees C (52 degrees F).
TAXONOMIC CLASS: Fine-loamy, mixed, superactive, isomesic Typic Palehumults
Soil moisture: The soil is usually moist in all parts in the soil moisture control section in most years, but becomes dry in the upper part for a time less than 30 days cumulative from approximately September 15 to October 15 in most years. The soils have an udic moisture regime.
Soil temperature: The mean annual soil temperature at 50 centimeters is 10 to 13 degrees C (50 to 55 degrees F). The difference between mean summer and mean winter temperature is 2 to 4 degrees C. The soils have an isomesic temperature regime.
Base Saturation: between 15 and 35 percent by sum of cations at 125 centimeters below the upper boundary of the argillic horizon.
Reaction: moderately to very strongly acid throughout.
Organic matter: greater than 0.9 percent organic carbon in the upper 15 centimeters of the argillic horizon.
Umbric Epipedon: 25 to 110 centimeters
Particle-Size Control Section (weighted average):
Rock fragments: 0 to 35 percent gravel, 0 to 7 percent cobbles, and 0 to 20 percent paragravels.
Clay content: 27 to 35 percent.
USE AND VEGETATION: This soil has been used for commercial timber production, wildlife, and watershed. Natural vegetation includes redwood, Douglas-fir, tanoak, western hemlock, Sitka spruce, rhododendron, evergreen huckleberry, redwood sorrel, and sword fern.
DISTRIBUTION AND EXTENT: California Coastal Redwood Belt; MLRA 4B. The series is not extensive.
