The waterfalls' water looked to be traveling at a great speed downward, where it finally crashed into the rocks below with such impact as to mistily throw itself upward again toward the heights from whence it fell. The rocks craggily jutted upward, daring the water to flow over their rough porous surfaces. Such a fearsome sight it was that I shuddered at the thought of any land creature so unfortunate as to be carried away with that wild and terrible fall.

Does that describe a word picture in your mind? I don't know if I can be an objective judge or not, seeing as I have seen the picture myself coupled with the fact that this is my carefully culled paragraph with which I may be inordinately pleased. :-
