• 4.0 RESULTS AND DISCUSSION
4.1 SOIL DESCRIPTIONS
Detailed mapping unit descriptions and general soil series descriptions
are contained in Appendices A and B respectively. The soil profile
descriptions of the 14 pedons formally described within the mapping area are
contained in Appendix C. Analytical data are contained in Appendix C. The
soil distribution map is contained in a map pocket at the end of the report.
Soil sampling locations are indicated by numerically labeled symbols on the
map and are correlated to the representative soil pedon descriptions in
Appendix B. Results of soil chemical and physical analysis are contained in
Appendix D.
4.2 SOIL CHEMICAL AND PHYSICAL EVALUATION
The mapping units Rock Outcrop (RO), Disturbed Lands (DL) and Stoneland
(5) have no recoverable topsoil. The Rock Outcrop unit is uncovered geologic
material which is too steep for soil to form. The Disturbed Land unit has had
the original soil mixed with geologic material in a manner that the soil is
now unrecoverable or the original soil has been compacted to the degree that
the bulk density is out of the soils range. The Stoneland unit has large
basalt boulders which comprise over 90 percent of the surface and profile.
• The vegetation which exists upon this unit is able to exploit the soil which
exists between the boulders. However, no technology exists to separate the
soil from the boulders without loss or destruction of the soil itself.
The mapping units Saraton Stoney Loam (2), Razor Stoney Clay (3),
Saraton-Beenom Complex (4) and Delson Deep and Delson Very Deep (1) all have
recoverable topsoil. The chemical and physical properties of the soils which
makeup these mapping units are best discussed on the soil series level. The
chemical and physical analysis data for the soil series are presented in
appendix D of this report. Analysis was performed by Bookcliff Labs, Inc. of
Steamboat Springs, Colorado. Following is a discussion of the chemical and
physical properties of the soil series, which make up the mapping units, as
to how the soils use as a reclamation material is affected.
DELSON SERIES
This soil series has no chemical properties which would hinder or
preclude its use as a reclamation material. The pH, EC, and SAR values for
this series indicate that there is no salinity or alkalinity problems
associated with the soil. The selenium and boron levels in each of the
horizons are far below those levels which are considered to be of
environmental concern for either plant or animal life.
The only physical characteristic of concern is the presence of
occasional basalt boulders. The basalt boulders makeup a very small
percentage of the total soil volume and are of no concern if they are placed
below the surface in the reclaimed areas. If the boulders occur on the
