Landing at the foot we were not long reaching the summit, although the thermometer was 90 degrees in the shade.

The river formed a remarkable feature in the landscape before us, to the north-east; and behind it rose a high table-range of hills, from five to six hundred feet in elevation.

These were capped with low reddish-coloured cliffs.
WHIRLWIND PLAINS.
At their feet stretched an extensive and seemingly boundless plain in a north-east direction, whilst on the south-east side, and distant about eighteen miles from where we stood, low ranges of hills were visible.
Here and there over the plains were many small whirlwinds appearing in the distance like streaks of smoke curling upwards through the air.
These, though affording relief to the eye in the wide prospect that opened before us, are fraught with danger when occurring on the river; for on one occasion they nearly upset the gig, and threatened to consign its crew to a watery grave.

In the present instance they gave an impulse to our invention, suggesting the propriety of designating the level tract of country before us, Whirlwind Plains.

The high land rising suddenly out of it, and bounding it very abruptly on the north-west side, we named Sea Range.
