 conspicuous of all is Half Dome. To the right (east) are two 

 huge bosses of rock, Mount Broderick and Liberty Cap, stand- 

 ing in the mouth of the Little Yosemite. These are typical 

 "roches moutonnees," knobs rounded and polished by the ice, 

 but too hard and resistant to be wiped away. Dome-shaped

FIG. 69. Tenaya Canyon, from Glacier Point. A U-shaped glacial 

 canyon. At the right is Half Dome, Basket Dome at the left. In the far 

 distance is Mount Hoffman, white with snow. Dark in center is Mount 

 Watkins. Below at the mouth of the canyon is Mirror Lake. 



masses of bare granite abound in the upper Yosemite region. 

 Most readily accessible to the sightseer is Sentinel Dome, which 

 stands on the upland southwest of Glacier Point. Several of 

 the domes were never overtopped by the ice of the glacial epoch. 

 Sentinel Dome stood above the highest level of glaciation. The 

 crown of Half Dome rose like a rocky island 500 feet above the 

 surface of the glaciers which coalesced about it.
