of the gold has probably been reconcentrated from this bench. The 
smaller portion of rough gold has probably a local source in the 
rocks of the creek valley. Drifting is done in the winter at a num- 
ber of places on the creek, but little information could be obtained as 
to results. 
LITTLE MINOOK CREEK. 
General description. — Little Minook Creek empties into Minook 
Creek about 5 miles from the Yukon and about 1^ miles above the 
mouth of Hunter Creek, and has so far been the largest producer of 
the region. In drier years it carries scarcely a sluice head of water. 
It has a grade of 100 feet or less per mile in the lower 3-mile section 
to which all the mining has been confined, and its course is remarka- 
ble in being nearly parallel to Hunter Creek, though considerably 
shorter, as it has a length of only about 8 miles. Like Hunter Creek 
it makes a sharp bend upon entering the high bench about 3 miles 
from Minook Creek. Above this bend Little Minook Creek has a 
maturer character, as shown by the more crooked valley and greater 
number of tributaries, while in its course through the bench it has a 
straight sharply V-shaped valley which has been cut to a depth of 
500 to 700 feet, and is so narrow that for over three months of the 
winter the sun can not be seen from the bottom of the valley. a 
The creek follows closely the southern side of the valley through 
its lower 3 miles, and mostly the western side above this. It seems 
likely that the greater accumulation of talus on the north side of the 
creek is due to the greater amount of sunshine it receives, resulting in 
a greater amount of breaking down of bed rock by alternate freezing 
and thawing. 
Gold was first discovered upon the creek in the early nineties by 
John Minook, who is reported to have taken out some gold near the 
mouth of the creek. The first claim, however, was located and worked 
by F. S. Langford in 189G, since which time the creek has been worked 
continuously. The total production of the creek is calculated, from 
the best ascertainable figures, to be $486,100, of which $40,000 was 
taken out during the winter of 1903-4 and $2,900 during the summer 
of 1904, making the output for the season of 1904 $42,900. 
Little Minook Creek heads among slates and quartzites cut by small 
decomposed acid dikes. A little over a mile below the head, the creek 
is crossed by a belt of clayey, nonfossiliferous limestone, accompanied^, 
as is often the case with the Rampart rocks, by green fine-grained 
slates. Below this there is an indistinct series of interbedded quartz- 
ites, cherts, siliceous shales, and some sandstones, all greatly contorted 
and accompanied by large masses of greenstones which form probably 
the larger part of the bed rock of the lower valley. At the foot of the
