occur on Shepherd creek three-quarters of a mile to the south. One occurs
in the hydraulic pit on Shepherd creek and others are exposed in the
canyon of that creek and in the upper part of Pine creek. They trend
northwest and some of them may extend nearly to the Thistle pit. There
is a very striking rock channel, filled with glacial drift, crossing Shepherd
creek and trending parallel to the road in the general direction of the
Thistle pit. It seems possible that the gold in the Thistle ground was
originally derived from this channel or from Summit and Pine Creek
valleys (See description of Pine creek) by glacial action and was later
reconcentrated by stream erosion of the glacial drift. There are no glacial
strie on the rocks in the vicinity which might furnish a clue as to the direc-
tion in which the ice moved, but it is reasonable to suppose that the ice
coming from the mountain slope to the east would tend to flow north down
the main valley at the foot of the mountain slope. In any case some of the
boulders in the deposits at the Thistle pit must have been derived from the
rocks of the mountain ridge to the east and southeast, for they are similar
to them and are unlike either the underlying rock or the rocks to the west.
It is reasonable, also, to suppose that the stream which formed the pay-
streak flowed down Big valley, for it is probable that, during the melting
of the ice previous to the last advance the deep valley to the east was
blocked by the ice and by glacial drift. Another fact which shows that the
pay-streaks in the old bedrock valleys of the neighbourhood were eroded
by the ice is that the materials hydraulicked in recent years on the west
side of the Thistle pit are glacial gravels included in the upper drift sheet.
There is no definite pay-streak, but large masses of the gravels included
in the drift sheet contain gold scattered through them.

The gold at Eightmile lake is fairly coarse and uniform in size, and is
much flattened and worn. The average colour is, perhaps, worth one cent,
although occasional pieces worth as much as $11 have been found. Its
character suggests transportation and sorting by a much more powerful
stream than exists at present in the vicinity of the lake. The former
stream came into existence, probably, as the result of melting of the ice.
The pay-streak is known to extend beneath the south side of the lake
where it is buried beneath tailings, but neither its total extent nor its value
is known. Mr. Ross holds that it trends southwest and not in the direction
of the Shepherd Creek cross-channel. As already pointed out the pay is
above the bedrock in the channel and, therefore, the stream that formed it
may not have been controlled in direction by the cross-channel, although
the gold may have originally been derived from it. The area beneath the
lake and in the general vicinity of the pit appears to be well worthy of
prospecting with the drill to determine whether there be sufficient ground
of value to pay for dredging. It does not appear possible to mine the
ground economically in any other way. ‘There are difficulties, however, in
dredging, as the boulder clay above the groundwater-level is hard, and
would probably require blasting to break it up; and there are numerous
large boulders in the deposits—especially in the lower part near the contact
of the two drift sheets.
