ground of the picture, to the top, a thickness of about one 

 hundred feet of soft sandstone. Seen from the east (Fig. 3), 

 a similar array is presented. F and G, underground stems, 

 shown more in detail in Figs. 7 and 6, are almost weathered 

 out and ready to fall. At F, it is interesting to observe two 

 corkscrews in close proximity, one twisting to the right, the 

 other to the left. At D an excellent specimen (similar to 

 Fig. 24, save the whorls were reversed, and there was no 

 ridge) was dug out and buried again, the drifting snow hin- 

 dering us from boxing it. 



It is from the west that Eagle Crag presents its most inter- 

 esting and diversified appearance. (See Fig. 4.) The cork-

screws are numerous and large, and especially accessible here. 

 They can be seen all the way from the one in the bottom of the 

 small caiion in the foreground at the left to those in the top 

 of the Crag in the background, a thickness of one hundred 

 feet. At A my first specimen, shown in Plate I., was taken 

 in 1891. At B is shown a large and excellent specimen, 

 figured in Plates II. and III. At C an open corkscrew, nine 

 feet high (plus an unknown amount not yet quarried out) 

 was secured. (See Plate IV.) At Z> a similar one was found. 

 At E (in a small blow-out) was found a corkscrew entirely 

 weathered out, figured in Plate V., Fig. 27. 



Pine Ridge is seen at P. R. Just to the right of C, cork- 

 screw logs project like so many guns in a fortress. These
