Tree-Ring Laboratory
Department of Geography
Portland State University

Lab Activities 1999 to Present

Dr. Keith Hadley, Director
Sharon Stanton, Research Assistant

The following is a list of presentations, manuscripts, theses, and grant activities supported by the
Geography Department's Tree-Ring Laboratory at Portland State University. Many of the lab's activities
have been completed in association with Dr. Karen Arabas, a Visiting Research Faculty Member at
Portland State University and an Associate Professor with the Department of Environment and Earth
Sciences at Willamette University. The lab's two computers, printer, and scanner are examples of
Willamette University's contributions to the lab. Undergraduate and graduate students from both
Portland State and Willamette universities have benefited from the collaborative operation of the lab
and are noted in several of the categories listed below.
