is strongly suggested from the general appearance of the 

 valley at this point, that the Bridal Veil stream grade at 

 some previous period had extended without interruption 

 FiV. 3 (b), in advance of its present 



position. In ascending 

 the main valley above the 

 constriction formed by El 

 Capitan and the Cathedral 

 Rocks, one finds oneself 

 inside a remarkable valley 

 whose steep and almost 

 inaccessible walls rise 

 from 3,000 to 4,000 feet 

 above the ilat floor. Yose-

 along a thalweg of moder- 

 ate steepness and then 

 plunging for 2,600 feet to 

 join the sluggish stream 

 below. (Fig. 4.) 



Some distance upstream 

 the valley again contracts 

 and the Tenaya Gorge 

 actually becomes V-shaped

 up into a series of large pamllelopipeds, which at times 

 almost represent irregular and uncemented masonry. At 

 frequent intervals also very large vertical and inclined
