Figs. A-F. — Station 13, canyon head near axis, 258-278 fins. 



A-F, Poorly sorted, gravelly silty mud; large subangular cobbles covered by 

 coelenterates (sea-anemones?) and a veneer of mud. Particularly large boulder 

 (>60 cms. diameter) is designated by arrow in C. Cloudy appearance of all 

 photographs suggest presence of substantial amounts of suspended sediment.
