Tropical Fossils in Alaska | Geophysical Institute
12 Dec 2025 at 4:54pm
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.
Cottonwood and Balsam Poplar | Geophysical Institute

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.
Northern Tree Habitats | Geophysical Institute
16 Dec 2025 at 4:57pm
Why take a chance with exotics, when native trees have proven their ability to survive? Several reasons prompt testing of foreign tree species. Human activities often create and maintain new, sometimes artificial habitats that native trees are not adapted to. Exotics may have strong wood, large fruits or straight boles that are lacking in the ...

Spruce trees planted on the islands by the Russians in 1805 are doing just fine and reseeding themselves naturally, although the total tree population hardly amounts to a forest.
Black Spruce | Geophysical Institute
15 Dec 2025 at 2:06pm
Somehow black spruce trees seem like the jackasses of the northern forests--sort of ungainly looking, ugly little beasts that somehow can survive under conditions prohibitive to the taller and more elegant birches and white spruce. But, like donkeys, black spruce have their likable and interesting qualities.

Granted, not all trees exhibit the same twist, but the majority of them do. The phenomenon can be likened to the claim that water will always spiral out of a drain in a counter-clockwise direction in the northern hemisphere.
The largest black spruce in Alaska | Geophysical Institute
6 Dec 2025 at 8:43pm
The Alaska champion black spruce tree stands on the campus of the University of Alaska Fairbanks. The tree lives in a mixed forest next to large white spruce trees, mature birch and a few alders and willows. The tree leans uphill, and its trunk is 45 inches around. When I hugged it, I could barely clasp my hands together.
Burls - Geophysical Institute
23 Nov 2025 at 4:02am
Burls weaken trees but do not kill them. The weakening effect, however, makes the trees vulnerable to other diseases which can kill them. Relatively little is known about burls, for several reasons: It takes a long time for a burl to grow--nearly as long as the tree on which it is found--so research is stretched out over a long period of time.

Tamarack -- Not A Dead Spruce | Geophysical Institute
11 Dec 2025 at 2:43am
When one of these trees finds itself on a better site, however, it shows a remarkable change of pace. Individual tamarack growing in white spruce stands may achieve a size comparable to white spruce 100 to 150 years old. The current record tamarack in Alaska stands near mile 311 of the Richardson Highway.
