WANDERING BOY VEINS.

Wandering Boy and Valley View conjugated veins. If the conditions on the 

 west side of Mizpah Hill, where the Valley View veins approach the Wandering 

 Boy veins, are like those on the east end near the Stone Cabin, the Wandering 

 Boy block, if depressed, should have brought down the vertical portion of the 

 vein, a condition which is not found. What the relative movement of the two 

 blocks has actually been is not certain. Siebert lake beds are exposed in the 

 southwest corner of the Mizpah Hill block, and are assumed, from the topog- 

 raphy, to occur in the southeast corner, but have not been actually observed 





FIG. 41. Hypothetical diagrammatic vertical cross section of the Valley View vein system (represented by its principal 

 and strongest vein) before faulting and erosion. The upper part is considered to b now represented in the Stone 

 Cabin and Silver Top workings and for a short distance below the outcrop of Mizpah Hill. The north vein is con- 

 sidered to be represented by the main vein in the Valley View workings, the south vein by that of the Wandering 

 Boy and Fraction. 



there. This indicates that the Mizpah Hill block has been depressed, relatively 

 to the Gold Hill block, so that the Wandering Boy vein would represent an 

 originally lower portion of the Valley View vein system than the portion now 

 outcropping on Mizpah Hill. If this is so, the vertical portion of the Valley 

 View vein system should be expected to pass in depth to veins dipping south at 

 angles of 30 or 40. From the Valley View workings, however, it is known 

 that in depth the vertical veins here actually pass into north-dipping veins and 

 continue so several hundred feet downward, at least. The north-dipping and the
