beaches between, but most of the coast near the entrance is bold and 

 rocky. San Pedro Point, which forms the northern limit of Coyote Bay, 

 is bold and rocky, but its connection with the mainland is low and sandy. 



Collecting in Concepcion Bay has been restricted to the Coyote Bay 

 area, where shore collecting, dipping by electric light, and dredging re- 

 ceived some attention. 



From Galleto Point, the northwest extremity of Concepcion Bay, it 

 is 4 miles to Colorado Point, where the coast line makes a long sweep to 

 form Santa Inez Bay, 8% miles across to Santa Inez Point, off which 

 are the three Santa Inez Islands. The coast here is lower, and the head- 

 land bluffs are not so high. Most of the shore in Santa Inez Bay is sandy 

 beach. 



From Chivato Point, 1% miles from Santa Inez Point, to Santa 

 Teresa Point, over 100 miles away, there are few distinctive geographic 

 features. The coast, in general, is low and sandy, and even the points may 

 be low, although some of them may be rocky. The depth of the water, as 

 elsewhere, increases rapidly offshore. The only harbor of importance is at 

 Santa Rosalia, 23 miles from Chivato Point, where two breakwaters 

 serve as a protection. Santa Rosalia is an important mining town, with 

 smelters. 



Lying off the southern part of this coast, 2% miles from shore, is San 

 Marcos Island, 5y 2 miles long and 1% to 2% miles wide. The eastern 

 and northeastern shores are bold and rocky, but the others are low, gen- 

 erally made up of sand beaches. A sandy shoal extends for some distance 

 south from the south end of the island. There are dredging stations to 

 the east, southeast, and south of the island. 



Tortuga Island, 2 miles by 1 mile, lies 15 miles northeast of the 

 northern end of San Marcos. It is rugged and barren, but some land 

 plants were collected from it. A series of dredging stations extend south- 

 ward from the southern shore, into 83 fathoms. 



Santa Teresa Point is a rocky bluff with a high hill back of it, the 

 whole forming a headland connected with the mainland by a low neck 

 of land, with sand beaches on each side. This headland forms part of the 

 boundary of two bays, Santa Teresa Bay to the south and San Francis- 

 quito Bay to the north. The northwest point of the headland is San 

 Gabriel Point, forming the eastern point of San Francisquito Bay. 



There are several dredging stations in and off San Francisquito Bay 

 and off San Gabriel Point, in depths to 165 fathoms, and in a great va- 

 riety of bottom.
