Edmund Schulman used a boring bit, a tool shaped like a drinking straw, to drill into old trees and pull pencil shaped pieces of wood called cores out of the trunks of very old trees. Cores contain patterns of stripes. One stripe represents one year of growth. Schulman counted more than 4,600 stripes from a tree he named Methuselah--after the oldest man in the Bible.
Today, the Methuselah Tree’s exact location is kept secret to protect it from too many visitors. Like all ancient bristlecone pines, Methuselah’s annual growth rings contain secrets spanning thousands of years—secrets that are being discovered by scientists who know how to “read” tree rings. Rainfall, fires, volcanoes, droughts, and climate changes, are literally recorded in the growth rings.
In the summer of 2011, I went searching for Methuselah. I brought along my camera. Although I am not a tree-ring scientist, I did my own research using my five senses. I tasted the pitch and pollen from cones (it was a little bit bitter); smelled the bark (it smelled like rain); touched wind sculpted and sun bleached wood surfaces (it was smooth and grooved); listened to the sound created when I tapped the rock-hard wood (it was sharp and short); and I was amazed by their strange forms and colors (they looked like dancers).
Did I find Methuselah during my adventure? Actually, when I stopped searching, Methuselah found me. I will share that story along with a lot of science, in the book I am writing. But I won’t publish Methuselah’s photo or location. Some things must be kept secret.
