THE CHANNEL: AT YOU BET AND BED DOG.

of verbal evidence that it had been struck only a few feet below the present surface of the gravel at a 

 number of other points. The character of the gravel - the clay, sand, and angular boulders - and 

 the dip of the bed-rock where seen seem to point to the filling up of a large basin after the main 

 stream had been choked by its accumulations. At any rate, high bed-rock has boon found in so 

 many places along Chicken Point that it is hardly possible for room to have remained for a deep 

 channel from the east or northeast south of or under the Sugar Loaf. It is true, there are some 

 jew places where bed-rock has not been actually reached] but if a deep channel exists at any of 

 these pomts, we should expect to see some signs of it in the character and stratification of the gravel 

 as well as at points farther up the ridge beyond the Sugar Loaf. It will also be noticed that 

 between the bed-rock on the Point and that in Wilcox Eavine there is a difference of altitude of 

 over four hundred feet, within a distance of less than three quarters of a mile, which would be 

 rather too much for the quiet deposition of gravel. 



In the mines at the base of the Sugar Loaf— those north of the Chalk Bluffs road and having 

 an outlet into the most southern fork of Missouri Canon — I saw no bed-rock at all, but determined 

 the altitude of the top of the present gravel, near the corner of the tool-house, to be 3,068 feet, 

 here was a depth of at least twenty feet of gravel here, as could be seen in the cuts and gullies 



worn by the hydraulic streams, but how much more it was impossible to tell. 



In Missouri Cation, which is now filled with tailings to a considerable depth, a spot was pointed 

 out to us, a few hundred feet below where the last observation was taken, at or near which bed- 

 rock used to be seen in the original bed of the canon. We, of course, had no means of determin- 

 ing its altitude with precision, but may adopt, as a rough estimate based upon the observations at 

 ^ozzens and Garber's shaft and in the Sugar Loaf mines, an altitude of 2,825 feet, 



In the Sugar Loaf mines it was noticeable that there was relatively much more sand and clay in 



ie gravel than at points nearer You Bet, reminding one rather of the Chicken Point gravel. There 



was also a considerable number of rounded lava boulders, increasing rapidly in size and frequency 



** ^ ie base of the bluff was approached. These had not been met with, or at least not noticed, on 



^ e south side of the road. From such indications it seems fair to conclude that the present high 



beT the h6ad ° f Misaouri Cafton is not P art and P are01 of the main dee P Yoa Bet channel, but 



c ongs rather (the top, at any rate) to the later period when the whole region was overflowed.
