The hydrogeology and water resources of Maine are closely related to the state's surficial geology, soils, climate, land use and environment. 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.
The Presumpscot formation is a late Pleistocene glacial deposit of predominantly submarine clays, located along the Maine and New Hampshire coast and inland along their major river valleys.
Glacial striations help determine the direction of a glacier; visible outcrops in the White Mountains, for instance, indicate ice flow toward the south-southeast. [14] 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]
The Cordilleran ice sheet covered up to 1,500,000 square kilometres (580,000 sq mi) at the Last Glacial Maximum. [11] The eastern edge abutted the Laurentide ice sheet. The sheet was anchored in the Coast Mountains of British Columbia and Alberta , south into the Cascade Range of Washington .

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 ...
Early people in Maine were influenced by a changing climate largely shaped by glacial processes. The Late Wisconsinan Laurentide Ice Sheet (LIS) covered Maine's landscape 35,000 years ago, extending far into the ocean. [3] As the climate warmed and the ice sheet retreated, Maine's landscape underwent deglaciation from 14,500 to 11,000 BCE. [4]
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 ...
