The plain, I have said, is everywhere broken by piles of stone forming knobby hills. Leaving the outlined sphinx to the right, we ascended a second block, which rises on the west of the chief watercourse, further down than the "Owl's Hill." The north-eastern flank shows the normal revetment of ruddy and black heat-altered grit, which gives a red back to the pale-sided, drab-coloured heap.
