Drunken trees, tilted trees, or a drunken forest, is a stand of trees displaced from their normal vertical alignment.
This most commonly occurs in northern subarctic taiga forests of Black Spruce (Picea mariana) under which discontinuous permafrost or ice wedges have melted, causing trees to tilt at various angles.
Tilted trees may also be caused by frost heaving, and subsequent palsa development, hummocks, earthflows, forested active rock glaciers, landslides, or earthquakes. In stands of spruce trees of equal age that germinated in the permafrost active layer after a fire, tilting begins when the trees are 50 to 100 years old, suggesting that surface heaving from new permafrost aggradation can also create drunken forests.

Famous quotes containing the words drunken and/or trees:
“[The Settlement House] must be grounded in a philosophy whose foundation is on the solidarity of the human race, a philosophy which will not waver when the race happens to be represented by a drunken woman or an idiot boy.”
—Jane Addams (1860–1935)
“Usually the scenery about them is drear and savage enough; and the logger’s camp is as completely in the woods as a fungus at the foot of a pine in a swamp; no outlook but to the sky overhead; no more clearing than is made by cutting down the trees of which it is built, and those which are necessary for fuel.”
—Henry David Thoreau (1817–1862)
