 Many of these species are characteristic of conifer forests elsewhere.

Outcroppings of basaltic rock are common in the Blue Mountains. 

 Besides the numerous small rock bluffs there are many rocky slopes 

 covered by broken pieces of rock of various sizes. These rocky slopes 

 often cover large areas. On exposed slopes grasses and small shrubs 

 such as ninebark {Opulaster pauciflorus) grow among the rocks and 

 in many places there are scattered yellow-pine trees (Pinus ponde- 

 rosa^. The habitat in such places often gradually gives way to the 

 yellow-pine forest habitat. 



Seventy-eight traps set on a rocky slope near Hompeg Falls cap- 

 tured 23 Peromyscus manieulatus gambelii and 2 Eutamias amoenus 

 amoenus on July 24, 1914.
