Yellacondas is obtained by going up the 
ravine east of Shingasanpully and crossing 
the mountains about a mile southfof the 
Gauly Conda Trigonometrical Station. 
* The results obtained by examining 
that line of country, together with a west- 
ward extension of the section, across the 
southern part of the Unkalumma Conda, 
are given in the annexed diagram (Fig. 35). 
The mountains are here seen to be formed 
by a series of two great anticlinals and 
synclinals followed by a great number of 
‘lesser foldings which pass under the Gauly 
Conda itself. 
* The westernmost anticlinal forms the 
great spur west of Shingasanpully, which 
lies in a valley formed by a great synclinal 
fold, the east side of the valley rising 
into the second anticlinal The second 
synclinal lies about 13 miles to the eastward, 
and its eastern side, ascending to the 
undulating plateau of the Gauly Conda, is 
very distinct. The smaller folds of the 
strata are very distinctly seen in the 
-deep picturesque ravine south of Pogulla 
(Goodsheltoora of map). The sides of the 
ravine form vertical cliffs, 80—100 feet 
high, of typical quartzites, which show the 
beds in very beautiful undulations, but 
unfortunately the ravine is so very narrow 
that but few of these curves can be seen at 
once. These undulations may be regarded 
as crumplings of a great flat anticlinal 
followed by some smaller folds and a nearly 
horizontal stretch of beds which disappear 
eastward by the sloping down of the 
mountain side into the Veddulcherroo valley 
in Nellore District. 
“The only part of this section which 
is doubtful is the second anticlinal fold. 
The exact position of the beds being ob- 
scured by intense cleavage.
