136 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 1 



extends % m ^ e southeastward to be continued as reef for some distance 

 farther. The point and reef form the western limit of Tepoca Bay, 2% 

 miles across, the western portion of the shore being low and sandy, but 

 the eastern with sand bluffs. Shore collecting has been done on the point 

 and on the reef, and dredging in the bay. 



From Cape Tepoca the coast turns eastward and then southward 

 again to Cape Lobos, 23 miles distant. The sand cliffs extend for some 

 distance, to be followed by a low, sandy shore. Cape Lobos is similar to 

 Cape Tepoca, sheltering Libertad Anchorage in the same way that Cape 

 Tepoca shelters Tepoca Bay. There are one shore station at Cape Lobos 

 and two dredging stations offshore to the northwest. 



From Libertad Anchorage, the coast continues in a southeasterly di- 

 rection for 36% miles to Cape Tepopa, with much the same type of coast, 

 but with less of a sweep than in the two previous bays. Like the other 

 two points, Cape Tepopa is a bold, rocky headland. Six and a half miles 

 farther on in the same general direction is Sargents Point, also high and 

 rocky, but it is connected with the mainland by a low, narrow neck of 

 land that may be submerged at high tide. West of this point, 5% miles, 

 lies Patos Island, which, except for a conical hill in the northwest portion, 

 is low. It, also, is white with guano. Collections of plants and insects have 

 been made on this island. 



From Sargents Point there is another sweep southeastward 20 miles 

 to San Miguel Point, with a much similar coast line. From 2% to 3% 

 miles off this part of the coast lies the northern half of the largest island 

 in the Gulf of California, Tiburon Island, with the northern extremity 

 4 miles south of Sargents Point. It is high and rugged but not so barren 

 as other islands in the Gulf, with a length north and south of 29 miles 

 and an average width of 15 miles. It is nearly rectangular, but the east 

 side is somewhat longer than the west. The north and much of the east 

 coast are low and sandy, but the remainder is bolder and more rocky. 

 Only the shore at the southeast corner is much broken. 



The southeast point of the island, not named on the chart, is a high 

 headland at the extremity of a peninsula that forms a bay, well protected 

 from the southeast winds. To the westward of this point, 3 miles, sepa- 

 rated from it by a narrow bay with a sand beach, is Monument Point, 

 the most southerly point of the island. Off this bay are Turners Island, 

 1% miles by % mile, Seal Rocks, and several other rocks and reefs. An- 

 other small bay separates Monument Point from Red Bluff Point, 2% 

 miles westward. West of Red Bluff Point, the coast again becomes regu- 

 lar.
