they were awakened, so they told us, by a loud hissing noise, and look- 

 ing northward saw that the heavens were brilliantly lighted, and 

 while rushing out of their tent saw a meteor fall somewhere north- 

 west of the mountain, between them and the railroad. We paid no 

 especial attention to their story, and supposed that although they 

 might have seen a meteor fall, it had come to the earth, if it came to 

 the earth at all, many miles distant. However, if we have been able 

 to fix the dates correctly, on the same evening, at the same moment, a 

 few minutes before nine o'clock, the hour being fixed by the train 

 schedule. Dr. A. Rounsville, of Williams, and Dr. G. F. Manning, of 

 Flagstaff, Arizona, were travelling to Canon Diablo station, where 

 Dr. Manning had JDeen called to visit a patient. Just before the 

 train stopped Dr. Rounsville saw from one of the windows, on the 

 south side of the train, a blazing meteor fall in the direction of Coon 

 Mountain. According to Dr. Rounsville's statement Dr. ^Manning 

 did not see the meteor fall, but only saw the very brilliant light 

 produced by it. It is very probable that this was the same meteor 

 that was seen by our employees at Coon Mountain. If so it would 

 appear that our two employees saw it from one side, while Drs. 

 Rounsville and Manning saw it from the other, the observers being 

 al^out 12 miles apart. As accurately as I can determine, it was very near 

 a spot at the intersection of the two lines of sight, a spot which of course 

 they could not locate exactly, that I found the above described meteoric 

 stone — the only one, so Mr. Volz, of Canon Diablo, tells me, that has ever 

 been found in this locality, and his intimate knowledge of the locality 

 extends for a period of over fifteen years. That a small stony meteor- 

 ite should have fallen on almost exactly the same spot on the earth's 

 surface as the great Caiion Diablo iron meteorite fell many centuries 

 ago, is certainly a most remarkable coincidence. I have stated the 

 facts as accurately as possible, and I have no opinion to offer as to 

 whether or not these involve anything more than a coincidence. 



I have endeavored to describe in this paper as briefl}^ as possiljle 

 only such matters as would appeal to a geologist and which have come 

 within my personal observation. Such as they are, after a very careful 

 study of this locality, they do not leave in my mind a scintilla of doubt 

 that this mountain and its crater were produced by the impact of a 

 huge meteorite or small asteroid, and that this fell upon the earth 

 almost vertically, with probably a slight inclination toward the north. 

 As is explained above, the greatest effort seems to have been expended 

 on the southern side of the crater, as evidenced by the walls of the 

 crater itself and by the great amount of material thrown out on the
