outlying butte. These five pairs of moraines possess the com- 
mon feature of distal curvature northward. 
Of the northernmost pair, issuing from Lundy eafion, the 
left-hand (northern) moraine is narrow and steep-sided—rising 
on both inner and outer sides at an angle of some 30° to an 
altitude of fully four hundred feet,—and curves northward so 
sharply as to almost follow the mountain-wall in which the 
cation is excavated. The inner side of the right-hand moraine 
8 equally steep and of concentric curvature; but its summit 
forms an undulating plateau half a mile broad, expanding, fan- 
like, toward its extremity, and sloping gently outwardly and 
distally toward the lacustral plain of Mono, into which it 
extremity the wave-marks becom

tral strata overlain by only five or ten feet of coarse littoral 
deposits, indicating that the glacier reached its greatest exten- 
Sion just before the waters attained their highest level.
