ciation for about a mile dowu stream. From that point down, 

 however, the main canon is glaciated, the ice having come in 

 from a side canon on the east which heads in a large cirque to 

 the northeast of Mt. Florence. A mile farther down another 

 glacier joined this from the southwest, heading in a cirque 

 in the northern face of the plateau remnant west of Mt. Van- 

 dever. A mile farther down stream another tributary glacier 

 came in from the east, which headed partly in the cirque to the 

 s >uth of Sawtooth, in which Silver Lake is situated, and partly 

 in another cirque still farther south. The confluent glacier was 

 800 feet thick just above Mineral King, as is well shown by the 

 large and well defined lateral moraine which flanks the west wall 

 of the canon, to that height, down to the point where the canon 

 turns abruptly to the west just at Mineral King. The crest of 

 this moraine is very sharply marked against the unglaciated upper 

 slopes of the canon, and it slopes down toward the north, or in 

 the direction of the flow of the ice. Just below Mineral King, 

 w i j re the canon bends westward, the glacier was joined by 

 another tributary which descended, by a series of steps with 

 glacial tarns, from a great cirque with rather steep floor situated 

 at the base of Sawtooth. This cirque is shown in Plate 43 a. 

 B 'low Mineral King the glacier arising from the confluence of 

 these various tributary ice streams is not known to have flowed 

 farther westward than about two miles. Beyond that distance 

 below Mineral King no evidences of glaciation were observed. 

 Only traces of a terminal moraine could he detected. This may 

 be due to the haste of observation, but in general the Alpine 

 glaciers of these mountains seem to have developed but feeble 

 terminal moraines, while their lateral moraines are often on a 

 vast scale. 



Along the western side of the crest of the Great Western 

 Divide there is a great array of shallow trough-like cirques which 

 followed paths now drained by the head waters of the Middle 

 Fork of the Kaweah. Several of these, the most southerly head- 

 ing near Sawtooth, originated ice streams which coalesced in 

 a large glacier flowing down the deep canon of Cliff Creek. 

 Great morainal embankments flank the sides of this canon, 

 where it is crossed by the trail from Mineral King to the Gian
