At Kansas City arc drift and loess, both resting on Carboniferous 

 beds. The loess is here, as elsewhere, a clayey loam, distinguished by 

 its tendency to cleave vertically and to stand in perpendicular walls as 

 a result of erosion, thus producing characteristic topographical forms. 



The road now takes a northwesterly direction through the State of 

 Missouri. After leaving Kansas City the loess continues as a conspic- 

 ous feature for miles, grading into loam and then into drift. The 

 substructure is formed by upper Carboniferous beds, which contain 

 coal seams of variable thickness and considerable extent, but which 

 have not been exploited on account of the proximity of the Iowa- 

 Missouri coal basin, in which the seams of the middle Coal Measures 

 are found at less depth. Midway between the Missouri and the Missis- 

 sippi the route crosses this basin, and gradually descends geologically 

 over the lower Coal Measures and the sub-Carboniferons formations, 

 the latter being well developed about the J)es Moines river. 



At Muscatine the road reaches Mississippi river, whose valley it 

 follows to the crossing at Davenport. 



The subterrane from the Mississippi to Lake Michigan is Paleozoic, in- 

 cluding Carboniferous, Devonian, and Silurian rocks. About Davenport 

 and Rock Island the Carboniferous rocks are brown sandstones, commonly 

 considered to have been deposited in outlying basins near the shore line
