PLATE 1 

 Fig. A. — Station 1, outer shelf, north of canyon head, 46-50 fms. 

 Figs. B-D. — Station 3, outer shelf, northwest of canyon head, 35-37 fms. 

 Figs. E-F. — Station 6, canyon head, northwest wall, 115-120 fms. 



A, Coarse shelly sand; faint, slightly sinuous symmetrical ripple marks with crest 

 orientation of 015 -19.1 "; abundant disarticulated pelecypod shells; 2 canceroid 

 crabs (arrows) and 1 fish (Urophycis) resting on bottom. 



B, Shelly, silty sand; straight short-crested asymmetric ripple marks (old); current 

 toward WSW; large articulated pelecypod shells, partially buried. Concave-up 

 attitude of the shells suggest weak bottom current activity. 



C&D, Bottom similar to B; ripple crests are sharper, with suggestion of current 

 interference pattern. Note turbid state of water in D. 



E, Sandy, somewhat shelly, silt; poor ripple mark development; ripple crest 

 orientation 145°-325°; disarticulated, partially buried pelecypod; small fish near 

 compass vane. 



F, Bottom similar to E. Compass striking bottom reveals muddy nature of bottom.
