Left the camp at 7.0 a.m., and followed the creek upwards to the east-south-east for five miles.  The valley was about one mile wide, with fine grassy flats, bounded by sandstone cliffs 50 to 200 feet high, and forming tableland with deep ravines.  The valley now turned to the east and east-north-east; some small tributaries joined the creek from the south-east, the sandstone cliffs disappeared, and the outline of the hills became rounded and rose about 300 feet above the creek.  Shallow pools of water with dry shingle between, and an occasional deep waterhole, characterised the channel of the watercourse.  At 1.30 p.m. camped on the left bank of the creek in an open grassy flat; the higher land very stony and indifferent.

The temperature was lower at sunrise this morning than on any other day since landing in North Australia, being only 41 degrees.  A little dew on the grass, and a light air from the east.  At 6.50 a.m. started and followed up the creek to the east-north-east till 1.0 p.m., when we camped at a deep pool of water 20 yards wide and 200 yards long.  Our attempts to procure fish were unsuccessful.  The country consisted of low stony hills, thinly wooded, and the flats of the creek from a quarter to three quarters of a mile wide continued to be well grassed.  On the north side of the creek a few miles back the hills rose to a greater elevation, and formed table-topped hills; some with cliffs of sandstone near the summits, and others smooth grassy slopes.  The latter, from the colour of the grass, appeared to be of trap formation, and fragments of this rock were found in the bed of the creek.  Soft shales were exposed in the gullies and on the sides of the hills, and were overlaid compact gray sandstones.

28th June.

Left the camp at 7.15 a.m., and followed up the creek to the east-north-east till noon, when we reached the last water in its channel near a steep range of sandstone hills, or rather tablelands; the country traversed was an undulating plain of trap formation resting on gray sandstone; it is thinly wooded, and well grassed; water was abundant in the creek below the camp; above the channel was dry, and soon divided into small gullies; in the afternoon ascended a hill three-quarters of a mile north-west of the camp; the lower portion was a dark compact trap or basalt, and the summit a horizontal bed of sandstone about 200 feet above the camp; the country to the north was very level, and only occasionally interrupted by flat-topped sandstone hills, the view extending at least thirty miles; to the south and south-west a country of trap formation extended for twenty miles, and to the east the tableland rose about 300 feet above the camp, and was composed of the same strata as the hill ascended, but surmounted by the ferruginous conglomerate, which is the highest rock of the new red sandstone series.
