90 FROM GREAT SALT LAKE CITY TO FORT HALL. 



between the Malade and the waters of the Port Neuf, the robd 

 descends by a gentle slope to the dry bed of a small stream, which 

 forms a narrow gorge ; emerging from which, and proceeding north, 

 we descended to a small stream forming one of the heads of a 

 branch of the Port Neuf. It flows at the foot of a spur of the 

 range of hills which constitute the dividing ridge between it and 

 the Pannack, (another affluent of the Port Neuf,) and rises in a 

 broad valley lying to the westward of the road. It is bounded on 

 the west by a high range of hills extending to the southward, and 

 in that direction forming the ''divide" between the waters of the 

 Malade and those of the Pannack. 



The secondary or lower hills in this valley seem to be composed 

 principally of white clay containing volcanic debris. Crossing the 

 stream, we left the cut-off altogether, and turning to the left, 

 crossed over this ridge, which, where we crossed it, is very high 

 and steep, and a mile and a-half in width. Descending its western 

 slope, we struck upon the heads of one of the main forks of the 

 Pannack, down which an excellent road can be obtained without 

 difficulty, the descent being moderate and the ground generally 

 level. 



Descending the valley of this stream, we encamped on its right 

 bank with plenty of grass, fine cool water, and a profusion of 

 willows for fuel. Day's march, fifteen miles. 



At the dividing ridge between the waters of the Port Neuf and 

 the Malade, the direction of the stratification has e^ddently changed. 

 Near the south end of the pass, an escarpment of dark limestone 

 is seen on the eastern side, lying on and conformable with layers 

 of feldspathic rock. A short distance farther on, the same rock is 

 again seen, overlaying the dark limestone, and with a dip of about 

 50° to the north-east. From this point the centre of elevation, 

 consisting evidently of this hypogene rock, appears to take a di- 

 rection to the north-west, striking the chain of hills continued 

 from the west side of the valley of the Malade. It is plainly to 

 be seen that this has been a region of great disturbance, which 

 did not cease until a period subsequent to the deposition of the 

 secondary rocks that repose on the limestones, although not con- 

 formable with them. Passing this ridge, several high conical hills 

 were observed on the right, which seemed to be formed of second- 

 ary rocks, the stratification of which was apparently much more 

 horizontal than that of the limestones. The dividing ridge be- 

 tween the Port Neuf and the Pannack is composed of dark lime-
