It does not seem possible that there was ever a deep channel flowing in either direction between 

 tbe two extreme points. Dutch Elat, or Thompson Hill, must have stood at a parting of the 

 ways • and it is very probable that there was another such parting between You Bet and Red 



Dog. . 



I formerly expressed the opinion, based upon the hasty and incomplete examination of 1870, 



that the Quaker Hill gravel would be confined to the south side of the ridge, and that there was 

 no connection through, under the lava, with the gravel deposit at Scott's Elat, on Deer Creek.* 

 I am now sorry to be obliged to say that at my second visit also I was so much restricted in time 

 that I was not able to extend my observations to the north side of the ridge, nor to make any such 

 survey as would be decisive. But since it has been proved by shaft-sinking and drifting that the 

 deep bed-rock at Quaker Hill is even deeper than any of our former estimates made it to be, it 

 seems to me more probable that the Scott's Elat and Quaker Hill gravels are really parts of the 

 same deposit, and that ultimately a connection between the two places will be established. In 

 harmony with this view I have represented the gravel as continuous through the west gap at 

 Quaker Hill on the manuscript map of this region ; for, even if the actual surface dirt is of a 

 tufaceous character, the gravel or the superincumbent clay may be expected at a depth of a few feet 

 only. This opinion, however, is not one in support of which I can give many reasons based upon 

 my own observations in the field, and it does not carry with it any belief in the existence of a 

 channel between Scott's Flat and Blue Tent, for which the advocates of the "blue lead" theory 

 are apt to contend. A further survey of this part of the ridge is very much needed. 



I have on a previous page alluded to the "deep channel" between Red Dog and Quaker Hill. 

 There is also a second line of gravel deposits lying to the east, skirting the base of Chalk Bluff, and 

 from three to four hundred feet higher than the deep channel, which demands attention. At You 

 Bet the gravel is continuous across the channel from the site of the town to the high bed-rock at 

 Chicken Point, but, to the north of Missouri Canon, the high gravel is separated entirely from the 

 low, the gravel of Darling's, Boston, and Buckeye Hills being quite distinct from that of Red Dog 

 and Hunt's Hill. I made a careful examination of this portion of the gravel from Chicken Point 



At both these localities there are some evidences of the existence of a "high 

 channel." The bed-rock along a line which can be traced for the greater part of the way with 

 greater or less distinctness seems to have a slight pitch to the east, and thus to form a west rim. 

 Along this rim at Chicken Point there are large quantities of blue quartz boulders, some of them 

 from six to ten feet in diameter, not much washed ; they differ very markedly in character from 

 the other boulders of the neighborhood. The eastern rim of the high channel must be looked for 



to Buckeye Hill. 



near or under the bluff, where there is at the present time a continuous bank from the farther end 

 of Chicken Point nearly to Hussey's mine, with the exception of one small projecting point of un- 

 washed gravel near Timmens's house. On Buckeye Hill the gravel has been nearly all removed 

 back to the face of the lava bluff. As previously stated,t the evidence in favor of any original 

 high channel of well-defined character is not very strong, though it is not at all unlikely that at 

 some time during the filling of the basin with gravel one of the shifting currents may have occupied 



this position. 



Since the year 1870 there have been several changes in the ownership of gravel property in 



this district, and similar changes may be expected from year to year. It did not seem worth while
