GEOLOGICAL ItEPOWT. 



I have stated above that the eountrv along our line of travel is a success 

 rolling prairies. The surface-deposits above the regularly stratified rocks of tin 

 formations are generally very heavy, and consist of dritt-sand, clay, -ravel, an< 

 at numerous points bowlders are scattered over the surface, partly ot granite, but 

 of a very compact, light-reddish quartzose rock. 



Water is mostly obtained at a depth of from 40 to 70 feet, at least in the I 

 portion of the district. The following sections of wells were obtained: 

 1. On the upland, 17 miles from Leavenworth: 



2 feet of dark clavev soil, highlv productive. 



)d; total depth, 52 1 

 ,iles from Leavenwo 



12 feet drift-sand. 

 25 feet joint-clay. 



:\ feet '< 'ravel, in which water was reached; total depth, 46 feet. 



4. On the ridge, 3S miles from Leavenworth: 



20 feet vellowish tough clay. 

 30 feet bluish joint-clay. 



II feet white and vellow quartz sand, in which a large supply of water was 

 obtained: total depth, (5<i feet. 



5. Near Oak Point, on the upland, about 56 miles from Leavenworth: 



4 feet soil like the above. 

 ->0teet vellowish joint-elav. 

 10 feet sand, mixed with some clav.
