El Grande died. The Wilderness Society - Conclusions on 'El Grande' (Eucalyptus regnans) Quote:
# The dead and hollow centre of the tree extended up to at least 60 (65?) metres from ground level.
# Further openings in the trunk were evident at approximately 20 metres.
# The fire had burnt to the tree and then had been drawing into the ground-level openings.
# The dry rot and wood inside the trunk had ignited and the configuration of draught holes at the base with outlet holes further up had acted like a furnace and chimney.
# The temperatures generated within the tree core mush have been extremely high, virtually "cooking" the tree from the inside-out!
# The external furnacing had extended to 60-65 metres where the flames appear to have exited from some hollow branches of this level. N.B. The charring is visible!
