Labratory of Tree Ring Research
A Great FREE Field Trip at the University of Arizona
Observe and Take Notes
Some vocabulary words and background information before the tour.
Tree ring diagram
The tour begins in the lobby with these HUGE tree samples!
The building is a "tree house" and the branches (metal pipes) blow in the wind,
but not for long...apparently they are very loud when your in the labs
Some REAL scientists at work :-)
A long strip is cut out of the tree from the center out.
Dendrochronologists can study the markings and rings from the radial slice.
More samples on the walls with great stories.
