few large, round bowlders of igneous rock. It is claimed that this 
gravel from the surface down will pay for washing, and that the pay 
goes into the bed rock to a depth of 1 foot. The pay streak is more 
than 100 feet wide. 
The gold on these claims is comparatively coarse, nuggets as large 
as one dollar being common, though the average pieces are smaller 
than one cent. On the lower claim the pieces of gold are probably 
finer than on the upper. The pay streak at the former place is 
reported to average 6 cents to the pan. The gold nuggets have a 
rough surface, showing that they have not traveled far. 
At the upper claim some sluicing has been done with water col- 
lected in a system of ditches on the surface of the bench. These 
ditches provide a limited amount of water when the snow is going off 
in the spring and after heavy rains in the fall. A ditch about 2 miles 
long has recently been dug to bring water from Rhode Island Creek, 
but except in a rainy season the water from this source will probably 
be insufficient for sluicing. 
Mining has been in progress on Eureka Creek, 1 or 2 miles east of 
Glenn Creek, for the last two years. These mines have not been 
great producers of gold, and the writer was unable to visit them. 
They are reported to be confined to a section of the creek bed 1 mile 
long, and situated nearly opposite the mines on Glenn Creek. 
Good prospects of gold are reported from Omega Creek and McKin- 
ley Creek in this region, and within a few miles of Glenn Creek. 
Their exact location is not known and they were not examined by 
the writer. 
During the last season gold prospects were found on Pioneer Creek 
and several other northern tributaries of the Hootlenana. These lie 
east of Glenn Creek and probably within 10 miles of it. 
One prospect hole was sunk to a depth of 65 feet in the gravels of 
Baker Flats. While no pay streak has been located, colors of gold 
are reported. It will require further prospecting to show whether 
these gravels are workable as gold placers. 
On Minook Creek and on its several tributaries, known as Hunter, 
Little Minook, Rubj^, and Slate creeks, placer mines were in opera- 
tion last summer. 
SUMMARY. 
In the vicinity of Glenn Creek the known gold placers are confined 
to the creeks and benches within an area about 1 mile wide and 2 to 
3 miles long, lying parallel to the north side of the Baker Flats. This 
area coincides roughly with the limits of a broad bench cut on bed 
rock, 100 to 200 feet above the level of the lowland. Two of the 
creeks carrying placer gold rise within this bench, while two larger 
ones are gold bearing only where they cross it. 
The bench generally is covered by a soil derived from the bed rock
