Fifty-six peat deposits in northern Penobscot, eastern Piscataquis, and eastern Aroostook Counties, Maine, were investigated for peat resources. The total yield is an estimated 35,196,000 short tons air-dried peat, predominantly sphagnum moss and reed-sedge types. This peat, suitable for horticultural and agricultural uses, also has higher heating values and lower sulfur contents than other peat.
