years old and older, and bears a close 
relation in species to the former stand. 
There are no new seedlings and no 
seeding is in progress. These areas 
were hard burned in 1910 and all the 
trees were killed. The nearest green 
trees on the windward side are one-half 
mile away. On the upper portion of 
the slope three western yellow pine 
seedlings were found, all growing in one 
spot. These were the only evidence of 
the species found on the Deep Creek 
area. Since the first fire much snow 
brush ( Ceanothus velutinus) has taken 
hold, and considerable grass sod now 
covers from 80 to 90 per cent of the 
surface and is considered a hindrance 
to natural restocking. Reproduction 
counts of this slope are given in Table 
VI.

more, no less? This takes us to 1919. 
Did the 1919 conflagration scatter seed? 
If so, it was distributed in advance of 
the fire, for no 4-year-olds appear on 
the double burn. As the 4-year-old 
seedlings were not so evident elsewhere 
on single burns, the source and disper¬ 
sion of the seed which produced them 
must have been local rather than gen¬ 
eral. It seems reasonable to suppose 
that this seed was carried from green 
trees located in draws a half or a quar¬ 
ter of a mile to the south. 
Observations and counts made in 
the 1910 burn on an upper southwest 
slope, Deep Creek, at elevations rang¬ 
ing from 4,300 to 4,500 feet, cover the 
area marked e on the map in Figure 1. 
In this area are two large patches on 
which the previous stand was 100 to 
125 year old white pine, Douglas fir, 
lodgepole pine, lowland fir, and alpine 
fir. The natural reproduction is 8 
TRAIL CREEK BURNS 
On the southwest corner of the large 
1910 burn a spur terminating at the 
elbow of the Trail Creek was studied. 
This is almost cone shaped and more 
than 1,000 feet high. The principal 
slopes are generally northwest and 
northeast. (See fig. 2.) Previous to 
the 1910 burn there was an excellent 
stand of mature timber here which con¬ 
tained a high percentage of white pine. 
On the northeast slope the stand con¬ 
tained principally white pine, hemlock, 
and larch; and on the northwest white 
fir, Douglas fir, and scattered spruce 
and alpine fir in addition. All species, 
except some big larches on the lower 
part of the northeast aspect, were 
destroyed by the fire. Every part of 
the surface was burned. The soil is 
deep and of good quality, except on the 
upper northwest aspect and on the
