LIFE ZONES OF CARLSBAD REGION 19 



zone is indicated by a few dwarfed Engelmann spruce 

 that reach up within about two hundred feet of the top, 

 and by many dwarf plants of the zone, such as Silene, 

 Arenaria, Saxifraga, Rhodiola, Sedum, Orthocarpus, 

 Erigeron, and Ligusticum. The whole southerly slope 

 of the peak is bald and grassy, while the northerly slope 

 is steep and rocky, and the narrow crests of two lateral 

 ridges give scant foothold for other than dwarf plants 

 and have little attraction to the birds and mammals of 

 this zone. Still in one brief visit to the peak I noted 

 Clark nutcracker, Townsend solitaire, and the pipit, 

 probably mere visitors from the extensive areas of the 

 zone in the mountains of northern New Mexico.
