Northern Tree Habitats - Geophysical Institute
27 Mar 2025 at 2:32pm
However, after seven growing seasons in Fairbanks, trees from the most northern homelands of the Dezadeash, Carmacks and Mayo areas of the Yukon are among the tallest, and the early starters from the south are now ranked at the bottom; although some of the trees from the Ft. Nelson area of British Columbia have maintained their relatively fast ...
Tropical Fossils in Alaska - Geophysical Institute
30 Mar 2025 at 8:16am
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.
Trees as Earthquake Fault Indicators - Geophysical Institute
3 Apr 2025 at 5:05am
Trees along faults often are killed by drowning because the faults tend to collect normal drainage water. In some instances, there are widespread tree kills caused by general subsidence. Killed by sinking caused in the great 1964 Alaskan earthquake, firmly stark forests of dead trees stand guard around the shore of upper Turnagain Arm, near ...
Burls - Geophysical Institute
24 Mar 2025 at 5:53am
Trees with burls seem to be found in a cluster; if one tree in an area has burls, it is likely that other trees around it has them too. This clumping is suggestive of leafhoppers or aphids transmitting the disease, but no conclusive evidence of this is known yet. Burls weaken trees but do not kill them.

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. It is well known that you can make it spiral out in either direction, if you give it a little shove first.
Mummified forest tells tale of a changing north
3 Apr 2025 at 1:33pm
The mummy trees of northern Ellesmere Island include a trunk of a pine tree four feet long and six inches in diameter. Each of the trees was at least 75 years old when it died. The ancient forest holds samples of the last real trees in the area before it became too cold and dry to support large plants, Barker said.

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. In recent years, trees have been planted at military bases along the chain, and the State is now shipping out seedlings for reforestation projects all over Alaska.
Cottonwood and Balsam Poplar - Geophysical Institute
26 Mar 2025 at 5:24pm
The Klukwan giant holds the national record for black cottonwood diameter. Its nearest rival, a tree near Salem, Oregon, does hold the national height record. 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.
Feltleaf willows: Alaska?s most abundant tree

These trees, which can live longer than 1,000 years, grow on the rainy coast from the Oregon/California border through British Columbia and as far north as Prince William Sound. The giants have in many areas died in large numbers, puzzling scientists who later came up with a non-intuitive theory of what killed them.
