With time these sediments were buried, and pressure turned them to rock. As long ago as 500 million years sand, mud and silt was transported by rivers to the floor of an ancient sea. 2008), and other plant macrofossils (R. Anderson et al. Acadia National Park is located in Maine. Although geologists know a good deal about rock formation on Mount Desert Island between 500 and 350 million years ago, the last 350 million years are a bit of a mystery. Dating back to the late 1800s, the trail to South Bubble and its precariously perched 100-ton Bubble Rock has lured scientists, artists, outdoor enthusiasts and first-time visitors for generations, long before the area was protected as Acadia National Park. The name was given to the island by French settlers who were the first to settle there, other than Native Americans. Each glaciation removed traces of previous ice sheets, leaving a record of only the last ice sheet to move through the region. This is the official Facebook page for Acadia National Park.

Terrestrial deposits of marine clays, raised shorelines like the cave on the Cadillac Cliffs trail of Gorham Mountain, and raised cobble stone beaches are all examples of the effects of this glacially caused depression and rebound. What kind of weather can you expect? No fewer than 26 mountain peaks rise above the island, some visible up to 60 miles at sea. Coves protected from strong wave action are made up of fine-grained material, such as Sand Beach. Sand Beach is composed primarily of bits and pieces of the shells and hard parts of marine life, such as mussels and sea urchins. Volcanic Flows and ash accumulated in the ocean basin, and formed the light-colored Cranberry Island Volcanics and deposited layers of ash in the developing Bar Harbor Formation. ORONO, Me.

All NPS fossil resources are protected under the Paleontological Resources Preservation Act of 2009 (Public Law 111-11, Title VI, Subtitle D; 16 U.S.C. Relevance Most of the rocks in Acadia National Park are granite (1). With rising sea level, peaks have become islands, and once rocky ridges have been transformed into headlands and peninsulas. Some chunks of bedrock melted in the intense heat, while others were suspended in the magma. At this point all three rocks were part of an ancient continent called Avalonia, lying somewhere between North America and Europe in the Iapetus Ocean. Around 360 million years ago, some of this magma cooled into granite, creating the fourth (and most famous) rock formation on Mount Desert Island. Acadia National Park was established to protect the area's spectacular scenic values, Maine's rock bound coast, its coastal and its offshore islands as characterized by the geologic features, natural history and the native plant and animal life. Rising sea level drowned the lower ends of valleys and produced the submerged or drowned shoreline typical of New England. The intrusive rocks cooled beneath the earth's surface, allowing the crystals of various minerals to form and grow. In some places, glacial debris is washed in by the waves, and finer material is removed, leaving cobbles and pebbles to be rolled and rounded by the surf. They do know, however, that after the collision of North America and Avalonia, Africa and Eurasia smashed into North America to form a huge supercontinent called Pangea. The Maine coast near Acadia is very rugged due to the fact that much of Maine, including Acadia National Park, is part of the complex and extensive Appalachian Mountain system. A 3.8-magnitude earthquake rocked Acadia National Park on October 2, 2006. As the climate warmed, more ice melted in the warmer months than accumulated in the winter. Multi-Sport Adventure: Sea Kayaking, Bicycling & Hiking in Acadia. Boulders carried 20 miles or more were left behind by the melting ice. The Presumpscot Clay has yielded a diverse, largely marine fossil assemblage. These collisions also pushed up the Appalachian Mountains. . Excellent examples include the emplacement of previously molten rocks as part of the Cadillac Mountain intrusive complex on Mount Desert Island, the granite on the Schoodic Peninsula, and the volcanic episodes recorded in the Cranberry Island Series.

Acadia National Park. Acadia National Park. Enter dates. The investigation provides ground-water information for a water-resources management plan for the park being prepared by the Park Service. As the glaciers receded, they filled a vast valley surrounding the mountains with meltwater, creating the Gulf of Maine. The 42,000 acres that comprise Acadia National Park include glacier-worn granite mountains, rocky cliffs, crystal blue ponds and lakes, and a dramatic coastline where waves collide spectacularly with dramatic headlands. One of the most popular and beloved of US national parks, Acadia National Park sits on the rocky shore of the Maine coastline. 1987; Barnhardt et al. Slumping of the greenish- gray clay has destabilized the stream bank and changed the course of the stream. Deposited by waves, these shell fragments are thousands of years old. These glacial erratics are found in valleys and on mountaintops. This book describes the flora, fauna, and geology of the park, as well as a number of the prominent trails that take you in . The collision pushed up a massive mountain chain and caused huge pools of magma to rise up under the previously formed Avalonian rocks. Geodiversity refers to the full variety of natural geologic (rocks, minerals, sediments, fossils, landforms, and physical processes) and soil resources and processes that occur in the park. The park is celebrated for its remarkable pristine beauty, scenery, and unique coastline terrain . Mount Desert Island is one of the most fascinating geologic features on the eastern seaboard. About this activity. Waves and currents continually modify the park’s shoreline. Invertebrates include foraminifera (protists that form “shells”), sponge spicules (Knox 1956), bryozoans (“moss animals”), bivalves, gastropods, the shell-dwelling polychaete worm (bristleworm) Spirorbis (Brown and Branson 1932), beetles, ants (Kilian and Nelson 2008), barnacles, decapod crustaceans (crabs, shrimp, lobsters, and allies), ostracodes (seed shrimp), and ophiuroids (brittle stars) (Brown and Branson 1932). Much of Acadia's landforms were formed by large glaciers slowly moving over the park, picking up rocks, carving the Earth, and sculpting the land. Meltwater streams flowing from melting glacial ice deposited sand and gravel in outwash deposits in front of the glacier or in deltas building along the coast (Lowell and Borns 1988). Soon the ice sheets were set into motion under the pressure of their own weight, at which point they became glaciers. Earthquakes occur at a low but steady rate in Maine and generally have magnitudes less than 4.8 on the Richter scale. From fascinating history to pristine wilderness, from waves battering the coast to quiet inland ponds, and from lush lowland forests to panoramic mountain views, this park has it all. Evidence of the glaciers can be seen just about everywhere: broad U-shaped valleys hold lakes, glacial erratics dot the landscape, as do glacial erosional scars like chatter marks, striations, glacial polish, potholes, and kettle ponds. But it's also one of the most popular, luring roughly 3 million visitors a year. As North America and Europe drifted apart, the Atlantic Ocean was born and North America moved north from the equator to its present location. The park’s Mount Desert Island, the largest of many islands located along the coast of Maine, contains Cadillac Mountain, the highest point on the U.S. Atlantic coast. Then, around 200 million years ago, Pangea started to break apart. In this stretch of the park, visitors can glimpse Sand Beach, Newport Cove and Great Head. Bedrock, glaciers, and the sea combined to shape the exceptional landscape of Acadia National Park. Sea level lowered to approximately 55 m (180 ft) below its present position, and streams cut valleys into previously submerged coastal areas and continental shelf deposits (Barnhardt et al. Accumulations of rock, gravel, and sand dammed valleys. This sediment—a combination of sand, mud, and silt—piled up in thick layers, and over millions of years the bottom layers were compressed into sedimentary rock.

At 1,373 feet, Sargent Mountain is the second highest mountain in Acadia National Park, and most likely the oldest lake in Maine(17,000 years) is found about 300 feet from its summit. Unlike much of the East Coast, which is sandy and flat, Mount Desert Island towers 1,500 feet above a rocky shore. While smaller than west-coast earthquakes, they do increase the potential for rockfall and mass wasting. The vast weight of the ice depressed the land surface, so that in Maine's coastal region the melting of ice was accompanied by an invasion of the sea. 2004).

She sent the park an email and thanked the park ranger who sparked her interest in nature, specifically through the geology and astronomy programs at Acadia. fact 2: The park's tallest point, Cadillac Mountain is the tallest mountain on the entire Eastern Seaboard, from the Arctic to the tip of South America. The Presumpscot Formation (or Presumpscot Clay; also called the Leda Clay) was deposited between 15,000 and 11,000 years ago (Richards and Belknap 2003). The surficial deposits in Acadia National Park record a remarkable interaction of glacial activity and sea level fluctuations. This made it the first national park east of the Mississippi. In the case of a beach open to the storm-driven waves of the Atlantic Ocean, only the largest boulders remain. Acadia is located in an area which has been subjected to hundreds of millions of years of geologic activity, including more recent glacial activity and coastal erosion. Roughly 20 million years later, a string of volcanic islands formed in the Iapetus Ocean, and ash from erupting volcanoes settled on top of the Bar Harbor Formation, forming a third set of rocks: the Cranberry Isles Series.
