Livingston, Mont. 
Ho. 9. Three and one-half miles south of Livingston, Mont . , 
the Yellowstone River merges from a narrow stretch of 
valley - the Lower Canyon - about 2 miles long. The 
river here cuts at right angles across strike of the 
sedimentaries which dip to H. at 18 to 20. The granite 
and gneiss at base of the section coxae in just above the 
Lower Canyon or at upper end. 
On west side, however, a fault interrupts the suc- 
cession near base of the section and for some hundreds 
of yards in vicinity cf this the exposures are imperfect 
and rocks much broken up. The section as seen on W.side 
of river follows.-
