into flags with a wavy structure, slightly false-bedded. The 

 dip varies from 17° to 20°. Th© beds that follow are a 

 lenticular dolomite, in quartzite, situated near sharp bend 

 of the stream (seen on the rise) ; calcareous bands, in flag- 

 stones, showing lamination by weathering; the flagstones, in 

 ascending series, become more calcareous and pass into 

 calcareous flagstones. A waterfall, having a height of about 

 20 ft., occurs on this creek, about one-eighth of a mile before 

 its junction with Parachilna Creek. The section continues 

 in flagstones, quartzites, gritty limestones, and calcareous 

 grits: dip S.W. at 20°. Some of the gritty beds are from 

 10 ft. to 15 ft. in thickness, and, in places, show ripple 

 marks. The hill, adjacent to waterfall, consists mainly of 

 gritty limestones, and has a height of from 200 ft. to 300 ft. 



In the main creek, around a westerly and southerly bend, 

 there is a sudden change in the dip, passing into intense 

 folding and a throw down, by fault, at 90°. The fault area 

 is well defined by walls that are vertical and 14 ft. apart — 

 the fault area is filled by fault-rock. On the eastern side of 

 the fault the dip is N. 65° W. at 40°. On the western 

 side of fault the dip is S.W. with numerous small thrust folds, 

 which extend for 100 yards. At the next bend, one-eighth 

 of a mile below the previous observation, the dip is W. at 

 30°. At one-eighth of a mile, further down, rapids are 

 formed by a bar of gritty limestone, overlain by flags, and 

 include a thin be.d of oolitic marble, 1 ft. in thickness, 'and 

 having a dip W. at 30°. At another one-eighth of a mile 

 distance, a second strong bar of gritty limestone occurs, 

 making a cliff-bank 500 ft. in height: dip S. 60° W. at 30°. 

 The beds form a synclinal fold. The beds underlying the 

 synclinal curve are oolitic limestones, 20 ft. in thickness, 

 and inferior to these there are impure wavy limestones, with 

 a dip S.W. at 20°. 



At this point I left the main creek and followed up a 

 small tributary which drains in from the north-east. In this 

 creek a striking fold occurs which crosses the stream, on the 

 eastern side, the dip is W. at 14°; and on the western side, 

 the dip is N.W. at 80°, in flagstones. Higher up the creek, 

 there is another throw down to N.W. at 67°-80°; the section 

 showing dolomitic limestone in beds from 12 ft. to 18 ft. in 

 thickness. At the head of the creek there are thick quartzites 

 which rise to a crest of about 300 ft. in height, with a 

 shoulder of quartzite, at a lower level; and a yet lower one, 

 of flagstones, which, latter, come down to the level of the 

 road about half a mile westward of the camp. 



Spent the second night in camp with the road-men. Next 

 day cut across country to Blinman. Examined travertine
