2. THE CHARACTERISTICS AND VARIABILITY ANTICIPATED WITHIN THE MAJOR SOIL DEPOSITS
ARE DESCRIBED IN THE TEXT OF THIS REPORT. SIGNIFICANT LAYERS, INTERLAYERS AND
LENSES WITHIN THE MAJOR DEPOSITS ILLUSTRATED FROM INTERPRETATION OF THE
BOREHOLE RECORDS. THE BOUNDARIES ILLUSTRATED ARE INTENDED TO HIGHLIGHT THE
VARIABILITY WITHIN THE DEPOSITS, WHICH EXHIBIT GRADUAL TRANSITIONS FROM ONE SOIL
TYPE TO ANOTHER. IN ADDITION, LENSES AND INTERLAYERS NOT DETECTED BY THE
SUBSURFACE INVESTIGATION WILL BE PRESENT BETWEEN BOREHOLES.
