are considered to represent actual ground water conditions.In impervious and
frozen soils,accurate determinations of ground water elevations cannot be obtained
within a limited period of observation and other evidence on ground water elevations

SOILS
CLASSI FICATION AND CONSISTENCY
CLASSIFICATION:Identification and classification af the soil is accomplished in
accordance with the Unified Soil Classification System.Normally,the grain size
distirbution determines classification of the soil.The soil is defined according to
major and minor constituents with the minor elements serving as modifiers of the
major elements.Minor soil constitutents may be added to the classification
breakdown in accordance with the particle size proportions listed below;(i .e.,
sandy silt with some gravel,trace clay).
no call -0-3%trace -3-12%some -13-30%sandy,silty,gravelly ->30%
Identification and classification of soil strata which have a significant cobble and
boulder content is based on the unified classification of the minus 3 inch fraction
augmented by a description (i.e.,cobbles and boulders)of the plus 3 inch
fraction.Where a gradation curve,which includes the plus 3 inch fraction,exists
(samples from test trenches and pits)a modifier is used to describe independently
the percentage of each of the two plus 3 inch components.If there is no gradation
curve incorporating the plus 3-inch fraction (as in auger holes),the plus 3-inch
material is described as a single component (i.e.,cobbles and boulders),and a
modifier is used to indicate the relative percentage of the plus 3-inch fraction based
on the field logs.The modifiers in each case are used as fol lows:
Scattered -0-40%Numerous ->40%
-
r-,
i
SOl L CONSISTENCY -CRITERIA:Soil consistency as defined below and determined
by normal field and laboratory methods applies only to non-frozen material.For
these materials,the influence of such factors as soil structure,i.e.fissure
systems,shrinkage cracks,slickensides,etc.,must be taken into consideration in
making any correlation with the consistency values listed below.ln permafrost
zones,the consistency and strength of frozen soils may vary significantly and
unexplainably with ice content,thermal regime and soil type.

Standard Penetration tiN":Blows per foot of a 140-pound hammer falling
30 inches on a 2-inch OD split-spoon except where noted.
Often the split-spoon samplers do not reach the total intended sample depth.Where
this occurs the graphic log notes a refusal (Ref.)and give an indication of the
cause of the refusal.Tight soils are indicated by a blow count value followed by a
penetration length in inches.The presense of large rock fragments is indicated by
a cobble and boulder callout following the refusal callout.In certain instances a
blow count of 100+may be listed to indicate tight soils where total sampler
penetration is possible with more than 100 blows per foot.

EXPLANATION OF ICE SYMBOLS
Perct:ntage of visible Ice has been grouped for the purpose of designating the
amount of soil ice content.These groups have arbitrarily been set out
as follows:
-0%
1%-10%
11%-20%
21%-35%
>35%
No Visible Ice
Little Visible Ice
Occasional Visjbi~Ice
Some Visible rc",
Considerable Visible lee
The Ice description system IS bdsed on tha t prcsenl"J by K.A.LineD,and
C.W.Kaplar (1966).In this system,which IS an ext.~nsion of the Unified
Soil Classification System,the amount and physical clldracteristics of the
soil Ice are accounted for.The following table IS a brief summary of the
salient points of their classification system as modified to meel the needs
of this study.
