392 GEOLOGY AND GOLD DEPOSITS OF THE CRIPPLE CREEK DISTRICT. 
All the veins show the usual type of narrow, sheeted zones, sometimes with only 
one prominent central seam. The Cheyenne on level 3 shows as a single seam of 
entirely oxidized ore. On level 7 the Cheyenne and West Victor veins lie closely 
together and two systems of seams appear, one dipping 70° SW., corresponding to 
the latter, and the other very steep, corresponding to the former. On level 10, where 
the Cheyenne vein was very rich, it appeared as a streak of brown mud 3 to 4 feet 
thick, composed of crushed quartz and limonite. On level 11 the well-defined vein 
with seams of fluorite dipping 60° SW. is a barren brecciated zone 2 to 4 feet wide. 
On the t.wo lowest levels the oxidized vein remains well defined by several strong 
seams, but the mineralization seems less prominent than on the upper levels. 
The Buena Vista vein on the various levels of the incline is a sinuous and narrow 
sheeted zone, at most 6 feet wide, and in many places very seamy and brecciated. 
Fluorite is present locally as a central veinlet, up to 6 inches wide. The seams are 
generally coated by quartz and more or less open. On the lowest levels this vein 
continues through breccia and phonolite as a system of narrow seams from 2 to 3 
feet wide, but becomes less distinct toward the north. At the crossing with the 
Empire State No. 2 the Buena Vista vein is not well defined. There is a slight 
alteration of the country rock in the sheeted zones by the introduction of pyrite and 
dolomite, but it rarely masks the character of the rock. The East vein is similar 
to the Buena Vista. The Klondike and Campbell cross veins, about 400 feet south¬ 
east of the Lee shaft, are vertical sheeted zones with little evidence of mineralization. 
On level 12 the latter is very wide and carries values of low grade. 
ORE SHOOTS. 
On the Victor vein system, in Isabella ground, there are at least six well-defined 
shoots. The southernmost, the West Victor, carries a small ore body reaching to 
250 feet below the surface and dipping 45° NW. On the East Victor vein in the 
same vicinity a rich shoot extended into the Isabella from Victor ground, also 
pitching northwest and attaining a width of 30 feet. It gave out 350 feet below the 
surface and is said to have stopped at flat seams in the breccia, some of which 
carried ore themselves. 
Next follows the big Cheyenne shoot, on the vein of the same name. It begins 
on level 3, 1,200 feet southeast of the Lee shaft, and continues, pitching 45° NW., to 
a line 25 feet below level 10, where it encountered a large body of dense phonolite in 
which it rapidly impoverished. The richest ore was found at this point, and 
furnished a carload of 27£ tons which is reported to have yielded $219,000. 
The Klondike and Campbell cross veins have yielded no shoots of importance, 
though small bunches of ore may occur on them close to the Buena Vista Vein. 
The shoots on the latter number three. The first is a narrow vertical chimney 
beginning on level 11, 400 feet south of the Lee shaft, and continuing to the surface, 
widening out here considerably and practically connecting northward on level 3 with 
the next shoot just north of the shaft. The second is also a vertical chimney at most 
100 feet in length, the width of ore on all of the shoots averaging 3 feet. It begins 
on level 12 and, like the first, widens on level 3, connecting with the Incline shoot so 
that near the surface there is an almost continuous ore body 1,600 feet long. The 
Incline shoot also begins on level 11 and is stoped continuously with greatly
