STAY FLEXIBLE, GROW OLD
By Michael R. Walker (BA ’90)HOW many droughts have there been since A.D. 303? The oldest known limber pine in the world, discovered last summer by grad student Bryan P. Tikalsky (BS ’05) as part of his climate studies with assistant professor of geography Matthew F. Bekker (BS ’94), might hold the answer.

“Twister” has bent but not broken in the powerful buffets of Wasatch-front winds near the Alta ski resort for at least 1,700 years. The next oldest Pinus flexilis is in northern New Mexico, a sad little sapling at only 1,670 years old.
