It consists of primarily silt- and clay-sized particles formed from the glacial abrasion of the feldspars, quartz, and micas of the region, carried by glacial meltwater and deposited below sea level before subsequent crust rising (isostatic rebound) elevated the deposits up to more than 300 feet (91 m).
The Maine Geological Survey began a continuing process of mapping sand and gravel aquifers beginning in 1978. Statewide, Maine receives an annual rainfall total of 42 inches or 24 trillion gallons. Up to 50% of rainfall runs off the landscape in rivers and streams, while an additional 30–40% evaporates or is transpired through vegetation.
Denton earned his Ph.D. at the Yale University in 1965, and was the first scientist from the University of Maine elected to the National Academy of Sciences. His primary interest is the geological history of large ice sheets and smaller mountain glaciers, and in particular the role of these ice sheets in Quaternary and late-Tertiary ice ages.
Abrasion also produces rock flour which is visible in glacial outwash plains across New England. Maine has some of the longest eskers in the world. [12] As the climate began to warm, the glaciers began to melt and drainage from meltwater under the glacier formed huge torrents of sediment that, when compacted, left a long and sinuous ridge or kame.
Whaleback Shell Midden is a shell midden, or dump, consisting primarily of oyster shells located on the east side of the Damariscotta River in Maine, United States.It is preserved as a Maine state historic site and was included as part of the Damariscotta Oyster Shell Heaps listed on the National Register of Historic Places in 1969.
A church was established in 1640. Near 1700, the entire settlement on this island moved to Star Island in New Hampshire to escape taxes imposed by Massachusetts (of which Maine was then a province). The heyday of the island was the artists salon that thrived there in the late 19th century, before the advent of artists' colonies as we know them ...
Jordan Pond is an oligotrophic tarn in Acadia National Park near the town of Bar Harbor, Maine. The pond covers 187 acres (76 ha) to a maximum depth of 150 feet (46 m) with a shoreline of 3.6 miles (5.8 km). [4] [3] [5] The pond was formed by the Wisconsin Ice Sheet during the last glacial period. Penobscot Mountain (1194 ft) rises to the west ...
Mount Kineo is a prominent geological feature located on a 1,150-acre (470 ha) peninsula that extends from the easterly shore of Moosehead Lake in the northern forest of Maine. With 700-foot (210 m) cliffs rising straight up from the water, it is the central feature of Mount Kineo State Park , a protected area of 800 acres (320 ha) managed by ...
