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