to the south. The high ridge between Sweeney's creek and 

 Hunter's creek is a good example of a synclinal ridge. From the 

 Cossatot the axis strikes a little south of west, the overturn flattens 

 down and is crossed by the Rolling Fork in 6 S., 32 W., the south- 

 west of the southwest of section 34. 



The New Hope Anticline. — The third axis is crossed by the 

 Little Missouri in 6 S., 27 W., in the southwest quarter of section 

 12. It appears to form the ridge upon which the western half of 

 the Star-of-the-West and New Hope road is built. The lack of 

 marked topography prevented its being followed further west. 



The Self Creek Overturn. — In 6 S., 26 W., section 11, northeast 

 quarter, is a good example of an overturn of the type shown by 

 E'F' in Fig. 14. This is probably a continuation of an anticline 

 crossed by Bear creek at the north township line of 6 S., 25 W., 

 section 4. The strike would carry it south of west to a probable 

 overturn in the top of Pine mountain south of Star-of-the-West, 6 S., 

 27 W., section 13. But the topography does not sustain that view. 

 The steep north side of the Pine mountain in 6 S., 26 W., has a 

 strike a little north of west. No outcrops were found in this part 

 of the ridge and all those found in adjacent territory have a strike a 

 little south of west, so that the ridge, though so marked, may not 

 conform to the structure in 6 S., 26 W. West of Star-of-the-West 

 the Pine mountain is deflected until it strikes about southwest, the 

 strike of the outcrops being the same. It ends abruptly at Fallen 

 creek. 



The Gentry Overturn. — South of Gentry post-office is a ridge 

 two miles long, starting in a high knob at the southwest corner of 

 section 7, 6 S., 25 W., and maintaining a height of one hundred 

 and fifty feet in a south of west direction to the Little Missouri 

 river. This ridge gives the appearance of being an anticline over- 

 thrown to the north. 



Bear Creek Anticlines. — An anticline is crossed by the Kirby- 

 Murfreesboro road in 6 S., 25 W., in the southwest corner of sec- 

 tion II. In the northeast corner of section 19, on a small tributary 

 of Bear creek, the dip suggests the presence of an overturn over- 

 thrown to the north ; this may be a continuation of the I^ittle Bear 

 mountain overturn. In 6 S., 26 W., the Little Missouri crosses an 

 anticline or overturn in section 24, the northwest quarter. 



The Little Bear Motmtain Overturn. — The Little Bear mountain 

 overturn is in 6 S., 25 W. It begins in section 22, eastern part, at
