One eye or ear witness tells of a storm both seen and heard within the Canyon and adds: "I have seen the lightning play and heard the thunder roll among the summit peaks of the Rocky Mountains, as I have stood on some rocky point far above the clouds, but =nowhere= has the awful grandeur equalled that night in the lonesome depths of what was to us death's canyon.... Again all was shut in by darkness thicker than that of Egypt. The stillness was only broken by the roar of the river as it rushed along beneath me. Suddenly as if the mighty cliffs were rolling down against each other, there was peal after peal of thunder striking against the marble cliffs below, and mingling with their echoes, bounding from cliff to cliff. Thunder with echo, echo with thunder, crossed and recrossed from wall to wall of the canyon," etc. (note 33.) Surely sudden and dreadful storms rage here. The loudest in North America, says an expert. Observe that the visitor just quoted notices the "roar of the river" in connection with the fury of the tempest. Now, the ancient visitor does the same. After directing attention to the sudden high winds, he says that a decidedly curious sight or spectacle (=king shun=) is the =keang= (a large main stream which receives tributaries) spreading abroad (=fu=) the =noise= of flowing water (=tsung=) in the =Ta-Hoh= or Great Canyon. The noise of the great river or =Keang= is thus noticed by the ancient visitor, who also declares that the =Ta-Hoh= or Great Canyon constitutes a decidedly fine or curious sight. And such in truth it actually is. "Imagine a chasm that at times is less than a quarter of a mile wide and more than a mile deep, the bed of which is a tossing, =roaring=, madly impetuous flood.... What an imposing spectacle; what a sublime vision of mightiness!" (n. 34). A great sight! say the Ancients. A Wonder of the World! say the Moderns. The roar of the river has never ceased since the ancient scribe, or his informant, passed that way. A modern visitor says: "The threatening =roar= of the water is loud and constant." Again, "The =roar= of its waters was heard unceasingly from the hour we entered it until the time we landed here. No quiet in all that time." (n. 35). One navigator tells of a "bore" in connection with the resounding stream. "In the stillness of the night, the roaring of the huge mass could be heard reverberating among the windings of the river.... This singular phenomenon of the 'bore,' as it is called, is met with but at few places in the world.... In the course of four or five hours the river falls about thirty feet" (n. 36.) Another explorer pauses at one spot in his amphibious career to note that "high water mark" can be seen "fifty, sixty, or a hundred feet above its present stage;" and "when a storm bursts over the canyon, a side gulch is dangerous, for a sudden flood may come and the inpouring waters will raise the river, so as to hide the rocks before your eyes" (n. 37).
