Paleobotanist Jack A. Wolfe of the United States Geological Survey at Menlo Park, California, has found a number of tropical rain forest fossils along the eastern Gulf of Alaska. These include several kinds of palms, Burmese lacquer trees, mangroves and trees of the type that now produce nutmeg and Macassar oil.
The Klukwan giant belies the belief that trees tend to get smaller the farther north one goes. Both balsam poplar and cottonwood have value for fuel wood, pulp and lumber.
These trees are now responding to fewer hours of sunlight by ceasing to flood their leaves with chlorophyll. The sudden lack of that green, energy-converting chemical allows the leaves to show red, orange and yellow pigments that were within the leaves all summer.
By late winter, intricate buildups of hoarfrost crystals have formed on wooden poles and other objects. Warming rays of the sun cause evaporation of whatever frost may have formed on the south side of vertical poles and trees. Conduction within metal poles causes enough heat transfer to entirely remove the hoarfrost crystals from the pole surface.
Stan Boutin has climbed more than 5,000 spruce trees in the last 30 years. He has often returned to the forest floor knowing if a ball of twigs and moss within the tree contained newborn red squirrel pups. Over the years, those squirrels have taught Boutin and his colleagues many things, including an apparent ability to predict the future.
