Sitting-lion forms and great bee-hives or domes are also the 

 expression of this apparent mutilation of once long rambling spurs. 



5. Double cliff slopes.— A feature characteristic of the dense 

 crystallines of Milford and its side canyons especially. Along the 

 bordering walls of these canyons the lower portion is often observed 

 to be absolutely perpendicular for as much as from 1,000 to 2,500 

 feet. Above these rise the characteristically even, but very steep,

rock slopes (Figs. 11 and 12), for other 3,000 feet. Usually the 

 sides rise for some 4,000 or 5,000 feet in this steep fashion (slope 

 about 50° to 60°), but in many places these tremendous lower per- 

 pendicular slopes come in. Just below the points of convergence 

 of two steep and deep canyons the feature is much emphasized. 

 Figs. 9, 10, II, and 12 illustrate the point.

 Associated with these double slopes of Milford are found deep 

 rock basins having fairly flat bottoms and almost . perpendicular
