Mountain Zone was quite as vigorous as within the basin itself, 

 but there resulted from these high glaciers no such confluent 

 trunk glacier as that which occupied Kern ( -anon. To the north- 

 east, however, the convergence of various glaciers gave rise to a 

 notable trunk glacier in the canon of Roaring River; and to the 

 north in the basin of Bubb's Creek the glaciation was apparently 

 even more intense than in the Upper Kern, and doubtless gave 

 rise to a large trunk glacier in King's River Canon by the con- 

 fluence of the ice streams from Bubb's Creek with those of the 

 South Fork of King's River.* 



Of this glaciation of the outer border of the Upper Kern Basin 

 •the writer's opportunities limited him to glimpses from the summit 

 of Mt. Whitney of the great cirques which indent the eastern scarp 

 of the Sierra, from Mt. Williamson to Cirque Beak, and to a 

 more or less cursory acquaintance with the cirques, glaciated 

 canons and moraines of the western slope of the Great Western 

 Divide from Little Kern River to Tharp's Beak. 



Along this latter belt of country the most southerly glacier 

 tracks observed are three shallow cirques on the eastern side of 

 the divide between the Little Kern and the South Fork of the 

 Kaweah. These appear to have sent ice streams down the slope 

 for not more than a mile or so. At the head of the Little Kern 

 a glacier came down from a series of cirques which indent the 

 southern edge of the high plateau remnant to the west of Mt. Van- 

 dever. This descended by a series of steps, each marked by a 

 glacial tarn, to the canon of the Little Kern. Here it was joined 

 by a short glacier from the flanks of Mt. Florence, and thence 

 flowed for about four miles down the Little Kern. No important 

 terminal moraine appears to have been formed at the snout of this 

 glacier, but huge lateral moraines were deposited notably on the 

 east side of the canon above the mouth of Shot Gun Creek. This 

 moraine has a height of perhaps 500 feet above the Little Kern, 

 and spilled over the crest of the spur which separates Shot Gun 

 Creek from the Little Kern into the basin of the former. 



North of Farewell Gap, in descending the East Fork of the 

 Kaweah River toward Mineral King, there is no evidence of gla-
