Aug. 19 Since we are moving camp today I will summarize the area around Big Lagoon which I have covered, insofar as its various aspects of topography, climate, and vegetation relate to vertebrate animal distribution probably.
The uplands in this region were all originally covered with coniferous forest except certain far seaward slopes with poor soil, as, e.g. the area farther N. on the map inserted at the end of today's journal entry. Logging, both selective and clean cut plus much subsequent burning has altered the vegetation
after p. 72.
