vii viii INTRODUCTION
Peat is a light to dark brown or almost black residuum formed by the partial decay and disintegration of plants that grew in lakes, marshes, swamps, or damp places such as heaths. It may be fibrous matted material composed of mosses, ferns, grasses, rushes, reeds, sedges, and woody material from trees and shrubs; finely divided plants so decomposed that their biological identity has been lost; or nonfibrous, plastic, colloidal, and macerated material deposited at the bottom of lakes or other bodies of water. The U.S. Bureau of Mines classifies three general types of peat. Moss peat is material derived from moss; reed-sedge peat is material derived from the reed, sedge, shrub, and tree groups; and humus peat is material so decomposed that its botanical identity has been obscured and its further oxidation impeded. The American Society for Testing and Materials (ASTM) defines commercial-quality peat as only that peat which has an ash content of 25 percent or less (American Society for Testing and Materials, 1969). To avoid confusion with soil-science terminology, in this report sphagnum moss peat is equivalent to fibric peat, reed-sedge peat is equivalent to hemic herbaceous peat, and humus peat is equivalent to sapric peat (Olson et al., 1979).
Peat has been used for many years in agriculture and horticulture primarily because of its ;;ibility to retain many times its own weight in water. It has also been used as a domestic fuel for hundreds of years. More recently, peat has been used by nations such as Ireland and the Soviet Union to generate electricity. At the present time, virtually all of the peat harvested in the United States is used in agriculture and horticulture. However, in light of the increasing costs of traditional energy sources, peat is being more closely scrutinized as an alternate fuel source.
Recent estimates suggest that there are as ·many as 6,000 to 8,000 individual peat deposits in Maine covering a total land area of 500,000 to 750,000 acres. However, only some of these peat deposits have economic potential. The Maine Peat Resource Evaluation Program was developed to provide a more comprehensive analysis of the State's peat resources. Investigations were generally limited to deposits at least 80 acres in size containing a minimum thickness of 5 feet of commercial quality peat (peat with an ash content of less than 25 %).
This report summarizes the work conducted in Piscataquis and Somerset Counties under the Maine Peat Resource Evaluation Program. It includes sketch maps, cores, and laboratory analyses upon which estimates of the resources are based. These data may be utilized to more accurately assess J the energy and agricultural potential of Maine's peatlands. Atlases I ' covering the following areas are also available: Aroostook County; ' Penobscot County; southern and western Maine; and Washington County.
1 THE MAINE PEAT RESOURCE EVALUATION PROGRAM
In July 1979, the Maine Office of Energy Resources, in conjunction with the Maine Geological Survey, began the Maine Peat Resource Evaluation Program. The Program, which was funded by the U.S. Department of Energy (DOE), was undertaken to determine the amount and. location of fuel-grade peat in Maine. Similar DOE/State Peat Resource Evaluation Programs are also being carried out in thirteen other states, including Alaska, Michigan, Minnesota, North Carolina, and South Carolina, whose programs began in 1979. Alabama, Georgia, Florida, Louisiana, Massachusetts, New York, Rhode Island, and Wisconsin initiated programs in 1980 and 1981.
Research on the fuel potential of Maine's peat resources began early in the twentieth century. The first investigations were conducted by Bastin and Davis (1909) and Soper and Osbon (1922) of the U.S. Geological Survey. They were followed by Trefethen and Bradford (1944) of the Maine Geological Survey. The Maine Peat Resource Evaluation Program was designed to build upon the peat research and inventory conducted in Maine by the Maine and U.S. Geological Surveys in the 1970's (Cameron, 1975; Cameron and Massey, 1978; Cameron and Anderson, 1979).
Two hundred thirty three areas containing peat deposits were evaluated under the Program (Figure 1 ). During the first field season (1979), 56 areas in Aroostook, Penobscot, Piscataquis, and Washington Counties were investigated (Cameron and Anderson, 1980a, 1980b; Davis and Anderson, 1980 ). Fifty areas in Piscataquis, Somerset, Aroostook, Kennebec, and. Waldo Counties were evaluated during the 1980 field season (Cameron and Mullen, 1982; Cameron et al.,· 1982 ). In 1981, research efforts were concentrated in the yvestern and southern counties where 56 areas were surveyed (Cameron and Mullen, 1983 ), and in 1982, 50 areas in Washington and southern Aroostook Counties were evaluated (Cameron and Mullen, 1984 ). During a brief final field season in 1983, 21 areas in southern Penobscot County were investigated (Cameron, in preparation). The results on a county by county basis of the Maine Peat Resource Evaluation Program are shown in Table 1.
GEOLOGIC SETTING OF MAINE PEAT DEPOSITS
Maine is part of the Northern Appalachian Province. Its bedrock consists primarily of metamorphosed sedimentary and volcanic rocks which range in age from approximately 350 to 600 million years and are intruded by numerous bodies of granitic rock (Osberg et al., in press). Both the granite bodies and the metamorphic rocks have been subjected to several episodes of folding and faulting, as well as millions of years of weathering, which have resulted in rounded mountains and well-established drainage patterns.

Much of Maine's bedrock is covered by sediments deposited during the episodes of glaciation that occurred in the last hundred thousand years. Large continental glaciers (as opposed to small alpine glaciers found in mountain valleys) spread southward from Canada until much of northern North America was covered by a sheet of ice hundreds to thousands of feet thick. These ice sheets·eroded the bedrock and deposited a blanket of clay, silt, sand, gravel, and boulders. As the last ice sheet retreated, much of southern Maine was submerged as the ocean inundated land that had been depressed by the weight of the great thickness of ice (see Figure 3 ). Between about 13,300 and 12,000 years ago ( Stuiver and Borns, 1975 ), fossiliferous marine sand, silt, and clay were deposited on top of the bedrock and glacial sediments (Thompson and Borns, in press). The ocean gradually receded as the land surf ace slowly rebounded.
Erosion by glaciers and deposition of glacial and marine sediments significantly altered preglacial morphology and drainage, creating environments favorable for the formation of peat. Streams and rivers were slowed or dammed. Ponds and lakes formed in bedrock basins or in poorly drained depressions, particularly those underlain by glacial or marine silt and clay deposits. Where drainage was impaired, the accumulation of undecayed organic material was enhanced.
4 FORMATION OF PEAT DEPOSITS IN MAINE
The development of economically significant domed peat deposits typically found in Maine normally progresses through five phases. During the initial phase (Figure 2a), the remains of aquatic plants, such as algae and pond weeds, accumulate over inorganic bottom clay in a pond. When a sufficient thickness of organic material is reached, rooted plants including bulrushes and pond lilies begin to grow. Continued accumulation of aquatic plant remains eventually begins to divert waterflow (Figure 2b) and allow the growth of grasses, sedges, reeds and mosses. Remains of these marsh plants, primarily reed-sedge peat, gradually fill in the basin (Figure 2c).

Figure 2. Schematic maps and cross sections of five stages in the development of domed peat deposits (after Cameron, 1975 ).
5 In the fourth stage (Figure 2d), the peat-forming vegetation spreads out beyond the margins of the original basin, forming a continuous flat surface. At this stage, surf ace water flowing toward the bog and ground water from adjacent aquifers lack the energy necessary to reach the centers of the peat-filled depressions. Because the mineral content of the water supply is greatest at the edges of the marsh, plants along the margins increase in variety and abundance. A less diverse plant assemblage including sphagnum moss becomes established away from the deposit edges. With time, the proportion of sphagnum increases.
When sphagnum moss becomes the dominant species, moss peat begins to accumulate in a convex mass or dome (Figure 2e ). In this fifth stage, streams and ground water can contribute to the water supply only along the narrow strip between the dome of peat and the mineral soil. This strip, called the moat, collects runoff from both the mineral soil and the slopes of the dome of sphagnum peat. Eutrophic marsh and swamp grasses, shrubs, and trees grow where they are fed by the nutrient-rich surface and ground water and soil, while the mosses and heath vegetation on the dome are oligotrophic, receiving nutrients solely from precipitation. A water table is maintained within the dome by capillarity.

Peat deposits in Maine may be covered by marsh, swamp, or heath vegetation according to the phase of peatland development. Floods and fires during any phase may have destroyed all or part of a peat deposit, while variations in climate or nutrient input may change the rate of growth and decomposition. Therefore, deposits in varying stages of development are common.
6 METHODS OF INVESTIGATION
Not all peat deposits are considered peat resources. A peat deposit is simply an accumulation of peat, whereas a peat resource contains enough commercial quality peat (peat that has an ash content of 25 percent or less) for economic exploitation. For use as a fuel, the peat must also have a minimum heating value of 8, 000 BTU/lb. Under the Maine Peat Resource Evaluation Program, deposits that appeared to be at least 80 acres in size with a minimum average thickness of 5 feet of commercial quality peat were considered for study. Actual field measurements often resulted in fewer acres of commercial quality peat.
Potential sites were selected using topographic, soils, and geologic maps; aerial photographs; and other previously published information available for the region to be investigated. These potential sites were ranked based on factors such as accessibility and the likelihood of a deposit containing significant peat resources. Using this ranking, the most promising sites were selected· for field study.
In the field, the extent of the deposit was determined by pace and compass traverses, with the bearing and spacing of the traverses dependent on the size and configuration of the deposit. At regular intervals along the traverses, generally 500 feet, cores were obtained with a Macaulay or Davis peat sampler. Samples were taken for subsequent laboratory analysis, and factors such as surface vegetation, type and distribution of peat (both horizontally and vertically), and geomorphic characteristics were noted.
Estimates of commercial-quality resources were made in accordance with ASTM standards (1969) and were based on acre-feet of peat where the peat is five or more feet thick and has an ash content not greater than 25 percent. Tonnage figures throughout the report are for air-dried peat {approximately 30% moisture). The formula used for converting acre-feet of peat to short tons of air-dried peat was orig,inally developed by Bastin and Davis, who summarized the procedure:
11 the quantity of peat in a deposit may readily be calculated with enough accuracy for practical purposes, by obtaining its average depth and its area, and that it will yield at least 200 tons of dry machine-made fuel per acre, for each foot in depth. 11 (Bastin and Davis, 1909, p. 24)
The formula is as follows:
(average weight in pounds Volume of wet peat In bog, of 1 cubic foot of Volume of wet peat in bog, in cubic feet machine-made peat) in cubic feet Number of tons of air------X------= dried machine-made peat 4 2,000 200 which the bog can produce (number of cubic feet of (pounds in short ton) wet peat equal to 1 cubic foot of machine-made peat)
7 IDENTIFICATION OF MAINE PEAT RESOURCES
Resource potential is determined by the chemical and physical quality of the peat and the thickness and areal extent of the deposit. These factors result from the various environments in which the peat accumulated. Environmental factors fundamental to the development and preservation 0f the deposit include: type of unconsolidated sediment and bedrock foundation; glacial processes that affected the surf ace morphology; surface and ground water regimes; climate; and influences of flooding, fires, and human activities.
A guide combining these environmental factors has been developed (Cameron, 1983; in press) and applied to the peat deposits studied. Each deposit was assigned a geologic setting code based on the system outlined in Table 2 and explained below. The setting code can be used to help predict whether or not a peat deposit may in fact be a peat resource.
The two primary headings for deposits in Maine are: I. Deposits within the region of maximum marine invasion, and II. Deposits outside the region of maximum marine invasion. The location of a deposit relative to the marine limit (Figure 3) is important. Isostatic depression of the crust by glacial ice, followed by a worldwide rise in sea level ( Stuiver and Borns, 1975 ), caused much of southern Maine to be submerged by the ocean. The fine-grained sediments deposited during this period of inundation provided settings particularly favorable to the formation of peat. The poor drainage caused by these silts and clays resulted in the development of wetlands in which peat could accumulate. In addition, climate, especially humidity, influences size, height, and amount of sphagnum in economically significant raised bogs. The area between the marine limit and the present coastline typically has relatively high humidity which is conducive to both the growth of peat-forming vegetation and the preservation of their remains. The July average humidity at 8 PM (EST) is greater than 70 percent (Visher, 1954, p. 186).
The secondary headings of Table 2 refer to the major categories of underlying bedrock. The topography of Maine, although modified significantly by glacial processes, is bedrock controlled. The type and structure of the local bedrock influences the shape and orientation of preglacial valleys and basins which provide the settings for peat bogs. In addition, such economically important indicators as ash content, trace-element content, pH, and the occurrence of marl are related, at least indirectly, to the local or regional bedrock.
The tertiary headings are based on a synthesis of factors related to surface and ground water regimes, permeability and water-table fluctuations, as well as past and present effects of fires and flooding or ponding. Surface and ground water flow rates, for example, affect soil chemistry and help control growth and decay of peat-forming vegetation. The greatest breakdown of peat fibers takes place in the zone of water table fluctuation where aerobic bacteria help produce reed-sedge and sphagnum peat. Extreme breakdown of peat fibers results in an ash content
8 that is too high for commercial quality peat. Introduction of clay or silt by streams also reduces resource potential by increasing ash content. In addition, a potentially economically valuable raised bog may be destroyed by fire, or a currently economically valuable peat deposit may be concealed by ponding.
PEAT RESOURCES IN PISCATAQUIS AND SOMERSET COUNTIES
A total of 49 deposits covering 12,952 acres and containing 22,683,000 short tons (dry weight) of peat in Piscataquis and Somerset Counties (Figure 3 and Table 3) have been evaluated under the Maine Peat Resource Evaluation Program. Tnese deposits range in size from 27 to 1,344 acres and in estimated resources from 37,800 to 3,204,800 short tons. Maps of individual deposits showing the distribution and depth of peat, core sites, and the surficial geology of the area adjacent to the deposits are shown in Figures 4-52. Cores showing the vertical distribution of peat and sediment as well as sample locations, and the results of laboratory analyses are also included.
