Aggregate lab data for the BEECEE soil series. This aggregation is based on all pedons with a current taxon name of BEECEE, and applied along 1-cm thick depth slices. Solid lines are the slice-wise median, bounded on either side by the interval defined by the slice-wise 5th and 95th percentiles. The median is the value that splits the data in half. Five percent of the data are less than the 5th percentile, and five percent of the data are greater than the 95th percentile. Values along the right hand side y-axis describe the proportion of pedon data that contribute to aggregate values at this depth. For example, a value of "90%" at 25cm means that 90% of the pedons correlated to BEECEE were used in the calculation. Source: KSSL snapshot (updated 2020-03-13).

Monthly water balance estimated using a leaky-bucket style model for the BEECEE soil series. Monthly precipitation (PPT) and potential evapotranspiration (PET) have been estimated from the 50th percentile of gridded values (PRISM 1981-2010) overlapping with the extent of SSURGO map units containing each series as a major component. Monthly PET values were estimated using the method of Thornthwaite (1948). These (and other) climatic parameters are calculated with each SSURGO refresh and provided by the fetchOSD function of the soilDB package. Representative water storage values (“AWC” in the figures) were derived from SSURGO by taking the 50th percentile of profile-total water storage (sum[awc_r * horizon thickness]) for each soil series. Note that this representation of “water storage” is based on the average ability of most plants to extract soil water between 15 bar (“permanent wilting point”) and 1/3 bar (“field capacity”) matric potential. Soil moisture state can be roughly interpreted as “dry” when storage is depleted, “moist” when storage is between 0mm and AWC, and “wet” when there is a surplus. Clearly there are a lot of assumptions baked into this kind of monthly water balance. This is still a work in progress.

Sibling Summary
Siblings are those soil series that occur together in map units, in this case with the BEECEE series. Sketches are arranged according to their subgroup-level taxonomic structure.

Geomorphic description summaries for the BEECEE series and siblings. Series are sorted according to hierarchical clustering of proportions and relative hydrologic position within an idealized landform (e.g. top to bottom).
Most soil series (SSURGO components) are associated with a hillslope position and one or more landform-specific positions: hills, mountain slopes, terraces, and/or flats.
Proportions can be interpreted as an aggregate representation of geomorphic membership. The values printed to the left (number of component records) and right (Shannon entropy) of stacked bars can be used to judge the reliability of trends. Small Shannon entropy values suggest relatively consistent geomorphic association, while larger values suggest lack thereof. Source: SSURGO component records (updated 2024-10-23).

Shannon entropy values close to 0 represent soil series with relatively consistent geomorphic association, while values close to 1 suggest lack thereof.

CA-2012-05-08-04 | Butte Area, Parts of Butte and Plumas Counties - 2006
Block diagram 3.—This diagram shows the interface of the Northern Sierra Nevada and Southern Cascade Mountains. Volcanic flows moved down the canyon of the West Branch of the Feather River, burying Sierra Nevada rocks, and partially filled the canyon, forming a volcanic plain. Subsequent geologic erosion has cut away the original plain of volcanic rocks and has left remnants surrounded by steep canyons. The area of alluvium shown near the bottom of the diagram is a bar of sediment deposited in the flatter volcanic reach below the steeper metamorphic reach (Soil Survey of Butte Area, California, Parts of Butte and Plumas Counties; 2006).

Block diagram 4.—This diagram shows the topographic difference between some of the volcanic Cascade and metamorphic Sierra Nevada landforms. Stream channels cut across the grain of the nearly vertically oriented metamorphic Sierra Nevada rocks. The resistance of the metamorphic rocks deflects the stream from side to side, forming an irregular topography. The volcanic flows traveled horizontally and buried the Sierra Nevada rocks, forming a dissected plateau (Soil Survey of Butte Area, California, Parts of Butte and Plumas Counties; 2006).
CA-2012-05-08-08 | Butte Area, Parts of Butte and Plumas Counties - 2006
Block diagram 7.—This diagram shows a series of glacial moraines. Early glaciers scoured and partially removed the original volcanic flows and produced glacial till derived mostly from volcanic rocks. Subsequent glaciers formed on the exposed underlying pluton and produced glacial till derived mostly from intrusive igneous rocks (Soil Survey of Butte Area, California, Parts of Butte and Plumas Counties; 2006).
