to the land canyon but has a somewhat smaller madient. Carmel Canyon joins 

 Monterey Canyon at 1100 fm (2000 m). Beyond the junction the main canyon 

 is somewhat witler with a relatively flat floor. This in turn connects with an 

 outer fan having channels like those off" the La Jolla Canyon, but these begin 

 at much greater depths, around 2000 fm (3660 m) (Dill et al, 1054). The 

 connection is not as yet clearly demonstrated, Menard (1960) reported a gravel

core from the fan channel and the writer found gravel in the canyon at a depth 

 of 835 fm (1530 m) (Shepard, 1951). The latter core showed the gravel at the 

 bottom of a graded layer, indicative of turbidity-current deposits. In many 

 ways the most impressive feature of Monterey and adjacent canyons is their 

 dendritic and trellis drainage pattern (Fig. 7), showing structural trends that 

 are similar to those on the land. 



The Mediterranean canyons along the south coast of France and the west 

 coast of Corsica are certainly the best known outside of those from western
