TOURTELOTTE PARK SPECIAL MAP. 95 
reached in the southern part of the topographical basin known as Tourte- 
lotte Park. In Section C, Tourtelotte Park special map, the Justice fault 
appears to have an upthrow to the east of about 100 feet, but this is only 
local and is owing to the downfaulting of a narrow wedge-shaped block 
included between the Justice and Sarah Jane faults, near the pomt where 
they converge and meet. The effect of the downfaulting in this block is to 
reverse the throw of the Justice fault, and to give the Sarah Jane an 
increased downthrow of 100 feet or so. Beyond the point where the Sarah 
Jane and Justice faults meet, neither can be traced any great distance to 
the south, and it is probable that both die out soon after uniting. 
To the north of the point of greatest development of the Justice fault 
there is a more gradual dying out of the throw, and the fault runs in the 
bottom of Spar Gulch to Copper Gulch, where it unites with the Copper 
fault and with what is known on Aspen Mountain as the Chloride fault. 
The Chloride fault, as exhibited in the Bonnybel mine, has a northwest 
trend and a southwest dip, and a downthrow to the northeast of 100 feet 
or more. Both the Justice and the Copper faults, but especially the latter, 
have diminished materially in throw by the time they come together. 
The displacement of the Justice fault in Spar Gulch is always a 
normal downthrow to the east, except where the movement has been 
complicated by east-west faults of later origin. On account, also, of these 
complicated east-west faults the average movement of the Justice is hard 
to determine, but it seems to be about 250 feet in Spar Gulch. 
The Justice fault belongs to a different system from the Saddle Rock, 
Sarah Jane, and other faults belonging to the Aspen Mountain series. 
While the faults of the Aspen Mountain series have been important loci of 
mineral deposition, the series represented by the Justice fault has undoubt- 
edly developed since the ore deposition. Apparently no ores have formed 
in place in connection with this latter system, but the faults have displaced 
the preexisting ore bodies, together with the inclosing formations. 
Copper fault—T he Copper fault has been given its name from Copper 
Hill, on the east side of which it runs. Copper Hill, in turn, has obtained 
its name from the Copper King shaft, which is situated on the top of the 
hill; but the name in either case does not imply any great abundance of 
the metal. This fault is one of the north-south series, and runs very nearly 
parallel to those already described. It has the characteristics which have
