Sample of source text used for inspiration in this piece:
When I finished my last letter I stated that we were within seven miles from an enormous line of ruddy cliffs which encircled, beyond all doubt, the plateau of which Professor Challenger spoke. Their height, as we approached them, seemed to me ill some places to be greater than he had stated -- running up in parts to at least a thousand feet -- and they were curiously striated, in a manner which is, I believe, characteristic of basaltic upheavals. Something of the sort is to be seen in Salisbury Crags at Edinburgh. The summit showed every sign of a luxuriant vegetation, with bushes near the edge, and farther back many high trees. There was no indication of any life that we could see.The piece in progress:
That night we pitched our camp immediately under the cliff -- a most wild and desolate spot. The crags above us were not merely perpendicular, but curved outwards at the top, so that ascent was out of the question. Close to us was the high, thin pinnacle of rock which I believe I mentioned earlier in this narrative. It is like a broad red church spire, the top of it being level with the plateau, but a great chasm gaping between. On the summit of it there grew one high tree. Both pinnacle and cliff were comparatively low -- some five or six hundred feet, I should think.
