SOUTH AND WEST ASPECTS 
The figures for the south and west 
aspects on this double 1870 and 1910 
burn tell quite another story. Tables 
XI and XII, which summarize data 
for strip d, show only 58 seedlings per 
acre. Only 12 per cent of these are 
white pine, while 54 per cent are lodge- 
pole pine; and practically no seedlings 
are younger than seven years. Three 
other separate observations on these 
steep south and west lower slopes at 
e, f, and g show no reproduction except 
a few lodgepole pines. These bare as¬ 
pects are typical of many other similar 
areas in the Magee district. They are 
the result of hard double burns, and 
are characterized by thin, rocky soil, 
much sod, grass, and patches of snow 
brush. In some cases Douglas fir trees, 
either singly or in groups, have sur¬ 
vived the two burns, but they have not 
given rise to any stocking whatever. 
Natural reproduction here during 13 
years has been practically nil. The 
double burns have, therefore, brought 
about these permanent sores—sites ex¬ 
tremely difficult to reforest, either 
naturally or artificially. We may as¬ 
sume that similar unfortunate condi¬ 
tions will follow on the steep south and 
west aspect on Deep Creek and Jordan 
Creek.
