<DIV STYLE="text-align:Left;"><DIV><P><SPAN>The soils of Yellowstone National Park were being mapped between 1988 and 1996 to provide better information about their nature and distribution. The coverage of the soils of Yellowstone National Park of 1996 provides baseline soil data at an Order IV level. The information can be used for site-specific work only after field verification. Aerial photography taken between 1969 and 1971, surficial geology maps completed in 1970's, existing digital maps (Habitat Types, Landforms and Parent Material, DEM etc.), and information from site observations were used. The map units delineate soil bodies that occur together in repeating patterns on the landscape. Map units include a combination of soils, mapped together to reflect the scale of mapping, standards for purity, survey objectives, and map readability (see section Entity and Attribute Information for details). Rather than making map units with predetermined interpretations in mind, major soil properties were grouped to maximize differences between groups and minimize differences within a group. This type of grouping allows the user flexibility in developing interpretations for specific interests. The location of each map unit is shown on the detailed soil maps. Each map unit and each soil in the survey area is described in detail, including soil properties that affect land use and potential. The ARC coverage contains about 5,000 polygons, and about 80 different map units, each a combination of soils. Primary attributes are in the .PAT file, described in the Entity and Attribute Information Section of this Metadataset.</SPAN></P><P><SPAN>Data were downloaded by the Wyoming State Geological Survey (WSGS) in January, 2020 for display on the interactive Geology of Yellowstone Map.

Objectives were to provide baseline soil data at
an Order IV level, meaning that soils are
classified and mapped at a scale suitable for
broad resource planning, and to provide basic
soils information for use in research, resource
management, and interpretive and educational
reasons. Resource management planners can use it
to determine the effects of different management
alternatives. Research personnel can use it to
plan site locations, correlate soil properties
with existing information, extrapolate site data,
and help place site data in a landscape context.
Ecologists can better place communities of plants
and animals into a landscape setting using soils
as a component of the ecosystem. Wildfire
personnel can use the information to predict
vegetation recovery, potential wildfire soil
damage, and suppression hazards. Teachers and
students can study patterns of soils and how they
relate to wildlife use, vegetation patterns, or
visitor impact. Specialists in cultural resources,
construction and buried services can use this
survey to locate which areas require more
intensive field studies.

In the first systematic investigation of soil
properties completed by Trettin (1986), 67 sites
were described and sampled. Extensive chemical and
physical analyses are available for these sites.
Based on complete laboratory analysis, all of the
mineral soils classified in Trettin (1986) had
mixed mineralogy. This conclusion, combined with
results from complete laboratory analysis on 20
additional pedons, supports our assumption that
all mineral soils in the park have mixed
mineralogy, with a few exceptions in particular
parent materials. For example, in neutral chloride
hydrothermal areas many Entisols have siliceous,
rather than mixed mineralogy.

We matched our maps with other ongoing and
completed soil surveys that border Yellowstone
National Park to the extent practicable, given the
differing objectives between surveys, their state
of documentation, and our map unit definitions. We
matched lines on the Gallatin National Forest soil
survey, making the best possible correlation with
our delineations and soil descriptions. However,
because this survey has been completed for some
time, we only changed the delineations of
Yellowstone National Park map units. The Bridger
Teton National Forest also has a completed survey,
but it is very broadly mapped and we did not
attempt to match it. We matched the soil
investigation at Grand Teton National Park
(similar to that on the adjoining John D.
Rockefeller Jr. Memorial Parkway), using a method
similar to the one used with the Gallatin National
Forest. The Targhee National Forest has an ongoing
survey due to be completed in 1998. Edgematching
for this area was treated slightly differently,
with the objective of approaching a seamless match
on our survey area boundaries. Map unit
delineations were intermixed on the boundary. We
used either survey's map unit descriptions
depending on the best fit on the ground. Targhee
National Forest map unit descriptions were used
where appropriate, after converting to our map
unit format.
1996-01-01
We described more than 1,100 soil profiles, their
environment, and their site locations. These sites
were selected as representative of the local range
of important features that influence soil
development and their relative extent in the park.
This resulted in a random sampling of soils and a
representative sample of the soil-forming
conditions that occur in the park. Described
properties include color, texture, degree and kind
of soil aggregation; consistence; location and
thickness of horizons; distribution of plant
roots; clay films; presence of carbonates;
chemical reaction (pH); and volume and character
of rock fragments. All horizons have an archived
box sample. Extensive site data were collected on
vegetation cover, habitat type, rock types in the
soil profile and on the soil surface, features
relating to soil drainage, signs of disturbance,
regolith characteristics, elevation, slope
gradient, aspect, slope shape and position,
landform, and location. All relevant data were
entered into digital databases that can be linked
to geographic information systems and analytical
software packages. We spatially referenced each
sample point in a digital format. Therefore sample
points could be selected within a particular
delineation or based on a wide range of criteria
that spatially represented any of the soil-forming
factors, e.g., all sample sites in andesitic rock
types, wet forest habitat types, alluvial fans, or
within soil map unit 1221. We used these
techniques for refinement of soil-forming concepts
and for descriptions of property ranges within map
unit and taxonomic unit descriptions. Each soil
taxonomic unit and soil map unit has a documented
set of sample sites and an associated digital data
base. The conceptual basis for all delineations
was also documented through the rule base.
Finally, each sample site has an archived
reference box sample of horizons.
1996-01-01
We used the soil sample and site properties to
develop predictive models of soil occurrence on
the landscape. The basic premise in these models
is that the kind of soil occurring at a given
location can be predicted by knowing the
quantitative or qualitative values of a set of
factors, i.e. the parent material from which the
soil is formed, the climate and vegetation under
which the soil has developed, the topography, and
its age. These models were based on theories of
soil development, soil-site relationships observed
in the Yellowstone area, and extensive site
observations of soil properties on the ground.
Each model is expressed in a quantitative "rule"
or If-Then statement with accompanying conditions
under which it is valid. We based these conditions
on the information we collected, scientific
judgement, and previous research data. Because
each factor was expressed in a digital spatial
data base available in a geographic information
system (GIS), the rules could be applied in a
logical order to predict soils' spatial occurrence
and distribution on a set of digitally produced
maps. Most rule conditions were expressed in
spatial data layers, though some required manual
modification. ======= ASSUMPTIONS IN
CLASSIFICATION: ======= -----> (I) Cation Exchange
Capacity (CEC) Activity Classes for Soil Families:
Cation exchange activity classes based on CEC to
clay ratio are used to modify mineralogy classes
in differentiating families of mineral soils as
follows: CEC/clay > 0.6: superactive; CEC/clay 0.4
to 0.6: active; CEC/clay 0.24 to 0.40: semiactive;
CEC/clay < 0.24: subactive; - Rock type mineralogy
largely determines the type and activity of clay
in soils (Dixon, J. B. and Weed, S. B. 1977.
Minerals in soil environments. Soil Science
Society of America, Madison, WI). For this reason,
activity classes in the park are based on the most
abundant rock type found in the soil profile. This
assumes that the clays are weathered from the
dominant rock type found in the soil profile with
the exception of sedimentary rocks. Because
sandstone is more resistant to local weathering
processes than siltstone, shale or limestone, it
often occurs in the profile yet contributes
relatively little to clay activity. All pedons
with laboratory analysis are classified according
to the above guidelines. All others are classified
as follows, based on analysis of 110 pedons with
laboratory data: (a) Andesite - superactive Basalt
- superactive; Dacite - superactive Granite -
superactive; Rhyolite - mostly superactive, a few
active Limestone - superactive; -----> (II)
Mineralogy Based on complete laboratory analysis,
all of the mineral soils classified in Trettin, C.
C., 1986 (Characterization of soils in Yellowstone
National Park - Project Report CX-1200-1B027. Ford
Forestry Center, Michigan Technical University,
Houghton, MI.) had mixed mineralogy. This
conclusion, combined with results from complete
laboratory analysis on 20 additional pedons,
supports our assumption that all mineral soils in
the park have mixed mineralogy, with a few
exceptions in particular parent materials. For
example, in neutral chloride hydrothermal areas
many Entisols have siliceous, rather than mixed
mineralogy. -----> (III) Percent Base Saturation:
Taxonomic classification of soils is sometimes
dependent on percent base saturation (%BS) of soil
horizons. The Mollisol order and some Inceptisol
subgroups have specific %BS requirements. The high
cost of laboratory analysis limited the amount of
calculated %BS data available to the soil survey
staff. A standard practice used in soil surveys is
to use pH values to estimate %BS after correlation
with existing data. Until recently, the Gallatin
National Forest "pH versus base saturation" curves
were used to predict base saturation in
Yellowstone National Park (Henry Shovic, Gallatin
National Forest Soil Scientist, personal comm.).
These were modified for the Yellowstone study area
because soil forming factors vary somewhat from
those used in the Gallatin area. Based on these
modified relationships, we concluded andesite
parent materials have %BS greater than 50% in all
horizons. For soils derived from parent materials
other than andesite, pH 5.5 and pH 5.9 indicate
greater than 50% and 60% base saturations
respectively. -----> (IV) Soil Moisture Regime:
The moisture regime for most of the park is ustic.
This regime was determined through comparison with
established regimes in neighboring survey areas
adjoining the park. Exception to the ustic
moisture regime are in hydrothermal areas where
the moisture regime is considered udic or moister
due to the continual presence of steam and
hydrothermal waters. -----> (V) Soil Temperature
Regimes: Based on unpublished weather data, most
of the park is assumed to be in a cryic soil
temperature regime. A small area in the north is
probably in a frigid soil temperature regime.
Soils in hydrothermal areas often have soil
temperature regimes (mesic, isomesic, thermic,
isothermic, hyperthermic, and isohyperthermic)
that are warmer than cryic or frigid. We
determined the boundaries between cryic and frigid
temperature regimes using relationships developed
in the adjoining National Forests. These
relationships correlate slope, aspect, and
vegetation to soil temperature (unpublished
documents on file in Yellowstone National Park).
The following guidelines are used to determine
cryic and frigid temperatures regimes in the park:
(1) The temperature regime for Yellowstone is
assumed cryic in all areas above 7,500 feet. (2)
Between 6,000 feet and 7,500 feet, the temperature
regime is assumed frigid if the aspect is south,
southeast, or southwest, the slope is greater than
25 percent, and the habitat type is any of those
listed below in (3). (3) Below 6,000 feet, the
temperature regime is assumed frigid on any slope
and aspect that has the following habitat types:
PSME/SYAL, PSME/CARU, PSME/SPBE, PSME/PHMA,
ARTR/FEID, ARTR/AGSP, mudflow mosaic, AGSP/POSA,
FEID/AGSP, FEID/AGCA. See Despain, D. G. 1990.

Boulder, CO. for the scientific and common names
associated with these abbreviations. We delineated
a frigid temperature regime zone in the northern
part of the park based on (2) and (3). All map
units within this zone are dominated by soils with
frigid soil temperature regimes. Outside of this
zone, soils with frigid temperature regimes are
treated as inclusions. Soil temperature data were
collected in hydrothermal areas by Yellowstone
soil survey staff between 1989 and 1995. Mean
annual soil temperatures within thermal areas
varied between 10 and 80 degrees C depending on
location. We found temperatures at depths less
than 40 cm were significantly effected by diurnal
variation, and temperatures at greater depths were
primarily determined by the relatively constant
input of geothermal heat.

Using the GIS and the rule based system, soil maps
were produced automatically during the survey
process. The draft maps were used as field sheets
in ground verification. Each iteration of maps
represented a stage of completion. We used the GIS
to flag unmapped areas (places where no rules
existed for that particular combination of soil
forming factors) and analyze those combinations.
We resolved each case by 1) using existing sample
points or taking more field samples in those areas
to develop new map units, or 2) combining the
areas with other map units. The process of mapping
was considered complete when 1) all areas were
mapped to an appropriate level of quality and
detail, 2) concepts represented by the map units
were logical and fit into the surrounding
landscapes, and 3) map units had adequate
background documentation.

We edited the final draft maps using manual and
computer assisted methods to match ground
observations and to meet quality and readability
standards. All map unit boundaries were verified
on the maps using remote sensing techniques, and a
sampling of each map unit was visited on the
ground to verify soil occurrence and distribution.
