The absence of the Tulare group from the Kern River area 
is probably due partly to its removal by erosion and partly 
to its being mantled over by terrace-deposits and other Qua- 
ternary gravels. 
An epoch of land-conditions and therefore of elevation pre- 
ceded the formation of at least some of the alluvial deposits, 
and it may have been during this epoch that the Tulare beds 
suffered most from denudation. 
The fresh-water or brackish-water facies of the Temblor 
beds is local; and, taken in connection with the local embay- 
ment in the shore line of this epoch, affords evidence of 
estuarine conditions along the lower portion of the Caliente 
canyon, and indicates the entrance at this place of a consider- 
able stream, derived doubtless from the contiguous portions 
of the Great Basin.
