Distribution; Spring antelope distribution is illustrated in 

 Figure 63. Observations were concentrated in the northeast 

 corner of the study area (Lay Creek and South Pork Foster Creek) 

 and along Lone Tree Creek and Little Pumpkin Creek in the east 

 and southeast portions. 



Summer antelope distribution was less concentrated than spring 

 (Figure 64). Most observations occurred in the northwest and 

 southeast portions of the study area, extending into the Poster 

 Creek area. Clumped observations along Little Pumpkin Creek 

 were partially due to frequent travel along that route. 



Similar to spring distribution, fall antelope observations were 

 concentrated in the northwest and southeast portions of the study 

 area (Figure 65). Winter observations (Figure 66) followed the 

 same pattern but were fewer and less concentrated. The winter of 

 1980-81 was extremely mild and of short duration, making delineation
