This is one in a series of pollen studies of post-Pleistocene peat and other pollen-bearing sediments in the Pacific Northwest. Bogs in British Columbia, northern Idaho, many parts of Washington, and in west central Oregon have been analyzed and the forest succession interpreted from the pollen profiles. A tentative climatic trend has also been suggested. It has been shown that most of the bogs had their origin soon after the recession of the last continental ice sheet, and thus record most of the postglacial forest succession in adjacent regions. This study is the second of Oregon peat deposits, and the author expects to make many more analyses in Oregon and other parts of the Pacific Northwest. Eventually, a correlation will be made of most of the pollen profiles and a picture of post-Pleistocene forest succes­sion and climate reconstructed for the entire region. Many of these peat deposits lie within different climax vegetation areas. This fact should aid in the interpretation of specific fluctuations and in the evaluation of the pollen profiles. The existence of the same species of forest trees in several climax regions with different climates should help to clarify the meaning of their pollen profile fluctuations rather than to confuse them.
