The tree known as Populus trichocarpa is called the Cottonwood tree, which can grow to 100 feet high and 6 feet wide. the bark is rough and dark coloured, thus black cottonwood. so look up and see how massive these trees are. If you go to rivers edge (thats the Vedder river) late summer and fall thousands of salmon swim by to spawn. At times you may see eagles there for dinner. Look up what else do you see?
