26 KING: KADAPAH AND KARNUL FORMATIONS. [PART 7. 
in the Goolcheroo and Tripetty ranges there are vertical cliffs of 
from 5 to 700 feet. From the foot of this scarp there is a steepish 
slope to the rugged, though still flat, western upland which is the first 
step or terrace of the Bala Ghat or Mysore country. This upland terrace 
is much more evident as a country above the proper Madras low-country 
or Carnatic, in its southern part or below the Goolcheroo range, than 
it isin the Bellary District, for the traveller in passing from Madras 
to Bellary vid Cuddapah passes over no sudden steps of elevation, the 
rise being gradual. 
The eastern edge of the field from the parallel of Cummum 
The eastern edge of Southwards is well defined as the Yellacondas, 
the fe which rise up abruptly, from the Nellore plains, 
often to an elevation of 2,000 feet above the sea. The eastern face 
of the ridge is very rugged in precipitous and steep sided ribs and 
rifts of bare rock, with occasional cliffy scarps. There is, however, 
no well defined and continuous cliffy scarp looking out on the plains 
below, as is the case with the western hills. The Yellacondas are 
in this way almost the reverse of the Goolcheroo and Tripetty ranges, 
the scarps, if any, generally presenting their faces inwards to the 
creat basin, while their steep backs slope sharply down to the plains 
outside. What scarps there are, are also not so well defined or 
conspicuous as those of the western hills, and they occasionally show 
on both sides of the ridge. The views of the Tripetty hills, Vencatigherry 
Droog, and Nagwarumeonda (see Plate I), will illustrate the different 
aspects of the eastern and western edges of the field. 
A peculiar feature of the eastern face is the very wide and gently 
Pee cot uo ans sloping talus which toes the abrupt slopes of the 
abrupt face. Yellaconda range. There is no such talus on the 
western or northern edges of the field.
