Figure JO. -Scatter plot of mean diameter and sorting of surface sediment samples. The lower the value on the ordinate, the better the 

 sorting of the sediment. Dot, — sediment collected from surface. Small triangle, — sediment collected from ice flows. The arbitrary 

 groupings are keyed to the overprinted pattern on figure 1 1.
