From the summit of these bluffs there is an extensive prospect of English 
Prairie, which appears to be about two miles wide, bounded by a range of hills 
with graceful slopes. 
About seven miles above English Prairie is Richland City, on the right, recently 
laid off; where there is a good landing for steamboats, the banks being about four 
feet high immediately at the river, but increasing in height a short distance back. 
The soil is light and sandy in the low lands, but improves in quality towards the 
bluffs. The population on this part of the Wisconsin is rapidly increasing. 
Five miles above Richland (which is situated in Township 9 north, Range 2 west, 
of 4th Principal Meridian), soft, easily-crumbling, white and brown sandstone is ex- 
posed, fifteen feet thick, presenting a waved outline. Above these beds there is a 
gradual slope to near the top of the hill, which is capped with magnesian lime- 
stone, I’. 2, which can be traced with some little interruption along the brow of the 
hills for two miles, gradually increasing in elevation, until it finally forms a mural 
escarpment of forty-five feet: dip slightly towards the east. 
At the upper end of the exposure, a bed of five feet of micaceous white and green 
sandstone was found, at an elevation of forty-two feet, resembling in lithological 
character the beds at Mountain Island, above F. 1, ¢, and containing Orthis, Lin- 
gulas, and remains of Trilobites; also fucoidal-like impressions, in yellow, laminated 
layers. Under it are forty-two feet of heavy-bedded white and brown sandstone. 
The whole height of this hill is two hundred and fifty feet, and it appears to be 
composed entirely of different members of F. 1. 
The river now winds for seven miles through alluvial lands, supporting a heavy 
growth of oak, hickory, bass, and maple, with a few pines and cedars. In Section 
25, Township 8, Range 3 west, of 4th Principal Meridian, about a mile below 
Helena, the rocks are exposed at intervals, as follows:
