drunken trees
A phenomenon in which trees appear to list to one side because the soil has shifted from melting of permafrost. Unfortunately seen more than ever because of global warming. In Alaska, what may be the worst example of this phenomenon in the world is continuing to happen, especially in and around the Kenai Preserve.
In the Kenai Preserve, four million acres of forest are dying. You can tell by the drunken trees and the "silvering" and sap loss from the spruces.
