APPEARANCE OF VEGETATION AROUND ANACONDA, 4l 
mountain had not been visited by fire during the life of the trees 
standing there in the summer of 1908. Practically all of the trees, 
however, were dead, although they showed no evidence of fire scars, 
with the exception of a few at the top of the mountain, as previously 
explained. 
In the locality corresponding, approximately, to secs. 17 and 20 
there were a few red firs which were all dead. A fire evidently had 
spread over the whole country in this vicinity between Mill and 
Warm Springs creeks about eighteen or twenty years before, but in the 
region of secs. 16, 17, 20, and 21 there were millions of lodgepole pines 
of about fifteen to eighteen years’ growth, practically all of which were 
stunted, their needles were all badly discolored and dying, and re- 
production over this area was evidently practically impossible. 
That these lodgepole pines had grown since the fire mentioned, and 
consequently could not have been injured by it, was shown by the 
fact that many of them grew by large stumps that were badly burned, 
and yet the lodgepole pines immediately adjacent were not fire 
scarred in the slightest degree. 
The ridge between Mill and Clear creeks was followed nearly to 
Mount Haggin, a point about a half mile into R. 12 W., returning 
by Clear Creek basin. The farthest point reached was approximately 
74 miles from the smelter. The fire of twenty years previous, 
already mentioned, evidently swept over this locality and destroyed 
many trees for quite a distance back on the ridge. A number of 
lodgepole pines, white pines, spruces, balsam firs, and larches, how- 
ever, were not killed by the fire, though the lodgepole pines were 
badly discolored and injured nearly as far up as they grew on the 
ridge. Even the white pines, which are quite resistant to smelter 
fumes, were injured for a considerable distance, but the damage 
to this species of trees did not extend so far back on the ridge. At 
the lower end of Clear Creek basin the lodgepole pines were badly 
discolored and injured; toward the upper end of the basin this injury 
was not so great, but could still be noted. 
Mill Creek Canyon was explored for a distance of 5 or 6 miles from 
the French Gulch road, which runs south from Anaconda to the 
divide. The farthest point reached was about 10 miles from the 
smelter. The fire of twenty years previous had run up this canyon 
for about 34 miles and destroyed many trees. Within this distance, 
however, some red firs escaped the fire and yet were dying in the 
summer of 1908. Young lodgepole pines that had come up since 
the fire were practically all discolored and injured and would evi- 
dently be totally destroyed in a short time. Beyond the range of 
fire injury the damage to lodgepole pines continued for some dis- 
tance, gradually dying out at a point about 5 miles up the creek. 
Injury to red firs was still apparent at the farthest point visited.
