Acadia National Park

Acadia National Park, Maine

Geography & History

Acadia National Park , near Bar Harbor, Maine, comprises 49,000+ acres of rock-bound coast on Mount Desert Island, a portion of the Schoodic Peninsula on the mainland, and offshore islands. Here in Acadia National Park you will find granite cliffs side by side with sand and cobblestone beaches. Glacier-carved mountains rise from the sea, cupping deep lakes in their valleys. Here, too, are meadows and marshes and dense evergreen forests. Everywhere the ocean makes its presence felt, whether by sight, sound, or smell.

Much of Acadia National Park's outstanding scenery is the result of glaciers carving through an east-west ridge of granite, leaving mountains separated by valleys. Many glaciers have covered Maine, and the last melted 11,000 years ago. Big blocks of ice were left behind forming lakes and ponds. As the glacier retreated, sea level rose and flooded the valley that is now the only fjord located on the eastern seaboard of the United States, Somes Sound.

Today a mixed coniferous-deciduous forest cloaks the granite backbone of the island, but the work of the glaciers is still evident in U-Shaped valleys, the whale backed ridges of the mountains, and glacial debris called erratics. The most prominent erratic is the huge boulder sitting atop South Bubble Mountain. It is thought to have been carried by the last glacier from some 50 miles away. The geologic sculpting of the island did not end with the glaciers, but continues today along the shoreline where the ocean constantly shapes and reshapes the rocky coast of Down East Maine.

Human history in the Acadia National Park area extends at least 5,000 years into the past. Shell heaps are evidence of native American Indian encampments. Explorer Samuel Champlain made the first European contribution to the area's recorded history when he landed on Mount Desert Island in 1604. It is he who named it Isle des Monts Deserts, island of barren mountains. The first visitors, artists of the Hudson River School of Art, arrived in the mid-1800s. Their depictions of the island lured others to experience its beauty. As word of the island's appeal spread, Mount Desert evolved into a favorite summer retreat for the wealthy Americans who transformed the landscape with elegant estates – called "cottages." From their ranks came a strong commitment to conservation. Concerned by development pressures, George B. Dorr, Charles Eliot, and others worked to preserve the land and ensure public access. They sought donations of private land and their efforts culminated in the establishment of the first national park east of the Mississippi River.

Thanks to their foresight and stewardship, today's generation, and future generations, can enjoy this island where the mountains meet the sea. Little did Secretary Lane know that 80 years later, millions, not thousands, of visitors from around the world would find "pleasure" at Acadia National Park annually. From sitting along the rocky shoreline in contemplation, to more active pursuits like hiking, there are numerous ways to explore this national treasure.
