100 T. W. Stanton — iStratigraphic Position 



From a point about one and a half miles north of Hilliard 

 another ridge of Cretaceous sandstone dipping 30° to 40° east 

 extends north and northwest for about two miles. The exact 

 relations of this ridge at the intersection with those just de- 

 scribed were obscured by surface debris, but it is evidently 

 composed of the same series of beds that constitute the other 

 ridges. The sandstone is underlain by a great thickness 1000 

 to 1500 feet — of fissile bluish and brownish shales not suf- 

 ficiently exposed for accurate measurement. 



Immediately west of Bear River City there is a prominent 

 ridge the crest of which is formed by a hard brownish con- 

 glomerate trending north 2S° east. It is nearly vertical and is 

 continuously exposed for about four miles. All the strata im- 

 mediately associated with this conglomerate and all those west 

 of it have approximately the same strike. These strata are 

 described* in Professor Meek's section on Sulphur Creek, and 

 as my first observations were made on the same section it is 

 reproduced here in order that the new facts may be clearly 

 connected with those already known. In copying the figure 

 (section 1) the first three beds at the east end of the section are 

 omitted, and names of the formations recognized are added 

 beneath. 



Meek's Section. 



"No. 1. Black shale, only seen in the bottom of Sulphur 

 Creek, thickness unknown. 



No. 2. Slope apparently occupied by clays, thickness per- 

 haps 100 feet or more .. - 100 ft. 



No. 3. Soft light grayish sandstone, nearly vertical .. 90 ft. 



No. 4. Covered space, probably occupied by clays, but 

 showing some sandstone that may or may not be in 

 place ; perhaps room enough for 250 to 300 feet 300 ft. 



No. 5. Two or three rather heavy beds of light yellowish 

 gray sandstone, separated by clays, probably occupying 

 some of the space included in division 4. Near the lower 

 part two layers 15 to 18 inches each, of sandstone, con- 

 taining Ostrea soleniscus, Trapezium micronema, etc. 

 Altogether 90 to 100 feet or more 100 ft. 



No. 6. Greenish and bluish gray sandy clays, with some 



dark shale at places 100 ft. 



No. 7. Bed of good coal, said to be 7-J feet in thickness.. 7£ ft. 



No. 8. Heavy massive bed of light colored sandstone, 

 about 90 feet in thickness, standing nearly vertical, 

 with some 3 to 5 feet of sandy clay between it and the 

 coal of division 7 95 ft. 



No. 9. Gray sandy shales with alternations of sandstone 



and clay - 255 ft,
