rocks in the soil prevent it from packing. The heaving action of frost 

 on the soil loosens the surface, often causing it to break into numerous 

 small cracks or fissures. If any juniper seed is deposited on this 

 area the chances of its germination and the establishment of the seed- 

 ling are exceptionally good. 



Page Flat is another large open area lying south of Cedar Glade. 

 Approximately 1,920 acres of this flat lie within the National Forest 

 boundary. The soil on Page Flat is of different composition from 

 that on Wagon Tire Flat. The soil is likewise moderately deep, but is 

 composed of disintegrated lime and sand stone, and malpais in about 

 equal proportions. It is a fine, compact, gravelly silt loam. 



The area is now overgrazed and sustains a number of species of 

 weed plants. Originally this flat carried a grama grass sod.
