Southern Washington stratovolcano

Mount Adams, known by some Native American tribes as Pahto or Klickitat, is a potentially active stratovolcano in the Cascade Range.

The climate of Adams gives it a large amount of diversity within its forests. On the west side, down in the lower valleys, grand fir and Douglas fir dominate the forest with Western hemlock and Western red cedar as well. On the east side, Douglas fir and ponderosa pine are dominant with some patches of dense lodgepole pine. Western hemlock and Western red cedar also occur but are limited to creek and river bottoms. Grand fir is present on sites with better moisture retention. At middle elevations on the west side, grand fir is increasingly replaced by Pacific silver fir and noble fir; and on the east side, lodgepole becomes much more prevalent. Above a certain elevation, lodgepole pine also appears in areas on the west side as well. As elevation increases, the forest changes again with subalpine fir, Engelmann spruce, and mountain hemlock becoming the dominant tree species on all sides of the mountain. Eventually, the last trees to disappear from the mountainside are the highly cold tolerant whitebark pine and mountain hemlock. Other conifers, 18 species in all, that play a lesser role than the dominant species are Western white pine, Sitka spruce, Western larch, Pacific yew, Alaska cedar, and mountain juniper. Adams is also home to many hardwoods as well including the tree species big leaf maple, Oregon white oak, quaking aspen, black cottonwood, and red alder. Large shrubs/small trees include the dwarf birch, Suksdorf's hawthorn, California hazelnut, bitter cherry, vine maple, Douglas maple, and blue elderberry and contribute to a vibrant fall display.
