Fig. 11. — North Face of Half Dome of Kings River Yosemite Valley 



leaned back in the shadow, and with slow action eroded the up- 

 per portion of the dome. All the rocks forming the south walls 

 of deep Yosemite canons exhibit more or less of this light after- 

 sculpture, effected in the shade after the north sun-beaten rocks 

 were finished. 



The south side of the dome has been heavily moutonee by 

 the Lyell Glacier, but is, nevertheless, nearly as vertical as the 

 north split side. The main body of the rock corresponds in form 

 and attitude with every other rock similarly situated with refer- 

 ence to ice-rivers, and to elevation above sea level, the special 

 split dome-top being, as we have seen, a result of special struc- 

 ture in the granite out of which it was formed. Numerous ex- 

 amples of this interesting species of rock may be culled from the 

 various Yosemites, illustrating every essential character on a 

 gradually changing scale.
