APPENDIX 



DRILL-LOG SUMMARIES 



The logs of 17 drill holes follow. The information is only a summary 

 of each log. 



Preliminary field data and the detailed descriptions from a binocular 

 microscope in the laboratory are included at the right of the column; the 

 tick mark indicates the center location of the sample taken. 



Grain size was estimated visually by comparison with sieved sediments 

 of known size. Sorting was estimated from the sorting chart of Folk (1968) 

 and the roundness chart of Powers (1953) . Depth in feet is logged to the 

 left of the column.
