The latitude of the water was 32 degrees 48 minutes S.and from it Mount Hall bore S.38 degrees W., Mount Cooper S.
15 degrees W.Before us to the north-east were visible many peaks of a range, with a high and broken outline, which I named the Gawler range, after His Excellency Colonel Gawler, the Governor of South Australia.

One very high peak in this range I named Mount Sturt, after my friend Captain Sturt; it bore from our present camp E.10 degrees N.and had been previously seen from the summit of Mount Hall.
September 20 .-- Our route to-day was through a perfect desert, very scrubby and stony, with much prickly grass growing upon the sand ridges, which alternated with the hard limestone flats; there were very few clear intervals of country upon our whole course; and for the last five miles the heavy sand and dense scrub made it very difficult to get on at all.
After a long stage of twenty-five miles nearly due east, we halted at a high ridge similar to that upon which we encamped last night, with sheets of granite exposed on its surface, and rain water lodged in the hollows.
The horses were all completely knocked up with the severe labour of this day's stage; I ascertained the latitude of the camp to be 32 degrees 47 minutes 40 seconds S.and the variation of the compass which increased as we advanced to the eastward, was now 4 degrees 12 minutes E.The Gawler range was now distinctly visible, extending from N.15 degrees W.to N.
65 degrees E.and presenting the broken and picturesque outline of a vast mountain mass rising abruptly out of the low scrubby country around.

The principal elevations in this extensive range, could not be less than two thousand feet; and they appeared to increase in height as the range trended to the north-west.

To the eastward the ranges decreased somewhat in elevation, but were still very lofty.
September 21 .-- We had another long stage to-day of twenty miles, over, if possible, a worse road than yesterday, no intermission whatever of the heavy steep sandy ridges and dense eucalyptus scrub; the horses were dreadfully jaded, and we were obliged to relieve them by yoking up all the riding horses that would draw.

Even with this aid we did not get the journey over until an hour and a half after dark.
