elevator has been installed to handle the flood-plain gravels, and active 
mining operations will be conducted during the coming year. 
MINING ON MAIN STREAM. 
Between Discovery Creek and Left Fork on Iron Creek the 1 re is 
fractional claim which has been worked for the last two years on a 
small scale. From one to five men have been employed on this claim 
all summer. The gold is coarse and easily saved. Both rusty and 
bright gold are found. The values occur in a thin pay streak on lime- 
stone and in the cracks and crevices of this bed rock. The small amoun 
of ground in this claim has prevented any large-scale developments 
At the junction of Left Fork and Iron Creek three men have been 
continuously employed all summer working creek gravels. Th 
method of working these gravels has been by means of a bed-rock 
drain and sluice boxes. Several nuggets worth $30 or $40 each have 
been found in this place. The bed rock is a much shattered limestone 
with thin bands of chloritic schist both above and below it. 
A short distance upstream from Left Fork the largest nuggel 
recorded from Iron Creek was found. This nugget weighed over 30 
ounces and was valued at $600 on the assumption that the gold was 
worth $18.50 an ounce. It is a fact of some significance that upstream 
from this point, which is about half a mile above Left Fork, the goi 
is all rusty, whereas below both rusty and bright gold. occur. Th 
reason for the absence of bright gold above is believed to be that thii 
point marks the place where the older and newer valleys merge. In 
other words, upstream the creek flows in the nearly unmodified old 
valley, while downstream it has cut below that level. The result of 
the down cutting has been to wear some of the gold and expose fresh, 
shiny surfaces; whereas the gold that has been practically unmoved 
has a rusty coating. 
Between Left Fork and Eldorado Creek only one camp was in opera- 
tion in 1 906. Five or six men have been at work at this place, but as it 
is understood that this portion of the creek has already been worke 
over three times it is doubtful whether subsequent work will beremu 
erative. The gravels are apparently similar to those already noted. 
Above Eldorado ('reek the main stream, as has been previously 
stated, is called Telegram Creek. One man only has been at work on 
this stream during the last year. This claim is located at a point 
about a mile from the divide. The bed rock is mostly graphitic schist 
with some thin limestone and schist bands. Several nuggets, worth 
as much as $100 apiece, have been found on this claim, and it is 
reported that very coarse gold is found even on the crest of the divide 
from Willow Creek. The water supply of Telegram Creek is small,
