Synopsis 



Although this set of photos 

 shows highway and urban 

 development, the geological 

 features of rock outcrops are 

 still apparent at the right center 

 of photos. The distant hills show 

 an increase in conifer density, 

 while deciduous tree species 

 have remained about the same 

 as they were in 1914 due to 

 land management practices. 

 Note the abundance of Yucca 

 glauca in the vegetation complex 

 in foreground.
