It will be seen, by an inspection of the map, that there is a large
interval of low depressed country, between Stanley's and Grey's Ranges.
The rock formation on the latter being almost exclusively of one kind.
Beyond Grey's Range, no elevation in the interior, on the N.W. line
traversed by the Expedition, was seen; but on the Stony Desert the
fragments of rock, with which it was covered, were composed of indurated
quartz, rounded by attrition, and coated with oxide of iron. North of the
Stony Desert, sandstone occurred in the bed of Eyre's Creek, and milky
quartz cropped out of the ground, in lat. 25 degrees
