106 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 1 



The conspicuous Consag Rock (Ship Rock), whitened with guano, 

 lies 18% miles east-northeastward of Point San Felipe. Around it are 

 several outlying rocks. Near by the water is shallow everywhere, and is 

 very muddy. Strong currents and tide rips are noticeable. Some shore 

 collecting has been done here, and there are several dredging stations in 

 the vicinity. In two of the hauls basketstars were abundant. 



The Velero III has not gone farther toward the head of the Gulf 

 than Consag Rock, but, according to the Coast Pilot, 



The coast from Point San Felipe to Sargent Point, at the mouth of the Colorado 

 River, about 38 miles to the northward, is low and backed by plains that rise 

 gradually towards the mountains in the interior. Mud flats and shoals that dry at 

 low water extend offshore l 1 /^ to 6 miles. Parts of this coast are subject to overflow 

 at times during heavy freshets and at highest spring tides.
