In British Columbia we had to core and date many Culturally Modified
Trees to determine if they were historic. This is the method we used:

Core the tree from the outer bark to the center of the tree.
Take another core from the deepest part of the scar to the center of the
tree.
Line up the cores from the center and count the difference in rings
between the two cores.

Subject: Los Angeles area dendrochronology?

Dear Hist-Arch'ers,
This query is on behalf of a student in our Modern Thought and
Literature
program, who is studying historic graffiti in Los Angeles, including
graffiti carved into trees. He is interested in whether dendrochronology
might be able to aid in dating the graffiti, some of which appears to be
late 19th - mid 20th century. The incisions are primarily on eucalyptus
trees. Does anyone know a LA-area dendrochronologist who might be able
to
assess whether this would be possible? 
Many thanks
--Barb Voss
