<br /> The substrata descriptions above are generalized representations and based upon visual/manual classification of cuttings and/or
<br /> samples obtained during drilling. Predominant material types shown on the log may contain different materials and the change from
<br /> one predominant material type to another could be different than indicated. Descriptions on this log apply only at the specific location
<br /> at the time of drilling and may not be representative of subsurface conditions at other locations or times.
