Far as the eye could reach to the south and east, the range
extended in a confused mass of peaks of great altitude, from the
sharp granite head of one thousand, to flat-topped basalt hills
of five or six thousand feet, and other conical points far
exceeding, and perhaps double, that altitude.
The Settite was very beautiful in this spot, as it emerged from
the gorge between the mountains, and it lay in a rough stony
valley about two hundred feet below our path as we ascended from
the junction of the Hor to better riding ground. In many places,
our route lay over broken stones, which sloped at an inclination
of about thirty degrees throughout the entire distance of the
river below; these were formed of decomposed basalt rocks that
had apparently been washed from decaying hills by the torrents of
the rainy season. At other parts of the route, we crossed above
similar debris of basalt that lay at an angle of about sixty
degrees, from a height of perhaps two hundred feet to the water's
edge, and reminded me of the rubbish shot from the side of a
mountain when boring a tunnel. The whole of the basalt in this
portion of the country was a dark slate colour; in some places it
was almost black; upon breaking a great number of pieces I found
small crystals of olivine.
