text: This record shows that peat formation has been continuous in all probability since the retreat of the local glaciers; that sedge peat of good quality accumulated in considerable thickness, absorbing water, retarding its runoff, and storing it to the point of saturation; that a change of water level intervened twice during the formation of a woody peat composed largely of material from two conifer forests; that the stand of timber in the older forest at the lower level was fairly dense and consisted of a mixture of hemlock, pine, "cedar," and spruce, while the succeeding forest near the 4-foot level above the glacial till was of slow and open growth and in small patches, hemlock being less abundant; that the present type of timber at the surface is mainly lodgepole pine, stunted, slow growing and widely scattered; and that sphagnum mosses have appeared only relatively recently in muskegs, as a readjustment consequent to poorer nutritional conditions that did not exist in these localities during the accumulation of sedge peat and woody peat below the surface near the base.
