Picture of the Day: Scaling the Mighty Redwood
SCALING THE MIGHTY REDWOOD
In this incredible photograph by Michael Nichols, we see two scientists partway up a 350-foot tree. Botanist Marie Antoine (at right) can be seen passing a core sample of the tree’s wood—750 years of redwood biography—to canopy ecologist Giacomo Renzullo. Research now shows that the older such trees get, the more wood they put on.
