Assateague Island National Seashore


The history of Assateague Island National Seashore is interwoven with indigenous culture and immigrant settlement. Indigenous people inhabited the region approximately 10,000 years ago, up until the 18th century when they emigrated from their native lands due to the European settlers’ influence. Native American tribes, such as the Assateague, lived harmoniously with the land, sustaining themselves with the island’s abundant natural resources. For food, they hunted, fished, grew crops, and traded with tribes as far away as New York and Ohio.

European explorers first encountered the island in the early 16th century. They were drawn to its bountiful landscapes. By the 17th century, European settlers established themselves on the mainland nearby, introducing their agriculture and trade to the area.

Assateague Island bore witness to numerous shipwrecks in the centuries that followed, adding an aura of mystery to the already captivating area. Local folklore tells tales of legendary horses, thought to be survivors of these maritime disasters, roaming the island freely and wild, further enhancing its mystique with dramatic tales.

By the early 20th century, the island had become a popular summer destination for vacationers seeking respite from city life. In the 1950s, it was zoned and sold as a private resort community. Within 5 to 10 years, the housing development firm that managed the land quickly realized the island was too unstable to sustain buildings and roads. In the 1960s, they sold the land to the federal government. To protect its unique ecosystems and wildlife, Assateague Island was designated as a national seashore in 1965, managed jointly by the National Park Service and the U.S. Fish and Wildlife Service and Department of Natural Resources. This designation ensured the preservation of its natural wonders as well as for future generations to cherish and enjoy.

Geology and Geography

Assateague Island is a dynamic and ever-changing landscape shaped by the forces of nature. Over its long evolution, it has come to home the longest beach in Maryland. The island itself began to take form around 15,000 years ago, during the end of the last Ice Age. The melting glaciers caused sea levels to rise, flooding low-lying areas and creating the barrier island. The island is part of the long chain of barrier islands stretching along the Atlantic coast, serving as a natural buffer between the ocean and the mainland.

Its geological foundation consists primarily of sand and sediment as erosion and run-off from the Appalachian Mountains. The longshore drift has moved and continues to move the sand, building and shaping the island’s length. As a result of the natural barrier process during storm activity, the island is continuously evolving westward. As water washes over the island, particularly during large storms, it sends sand backward toward the bay, which creates a rollover effect. This process is also accelerated by climate change and rising sea levels.

Assateague Island’s geography is characterized by its diverse ecosystems, including marshes, forests, shrublands, grasslands, dunes, and sandy beaches. As mentioned earlier, the island divides into two parts. The Maryland district to the north covers about two-thirds of the island, and the Virginia district to the south covers the remaining one-third. The state line between Maryland and Virginia cuts through the island, adding an interesting geopolitical dimension to its conservation management.

Flora and Fauna

The coastal bays, estuaries, and salt marshes surrounding the island provide essential habitats for a plethora of wildlife species. The island is renowned for its birdlife, attracting birdwatchers eager to catch glimpses of migratory species like sanderlings, piping plovers, and red knots. Additionally, the island is home to a remarkable diversity of fauna, including wild horses, white-tailed deer, red foxes, raccoons, black rat snakes, fiddler crabs, and various other animals found on land and in the Atlantic Ocean.

However, the most iconic residents of the longest beach in Maryland are the wild horses, famously known as the “Chincoteague Ponies” in the Virginia district and the “Assateague Horses” in the Maryland district. These horses are believed to be descendants of early settlers’ domesticated horses, which either escaped or were abandoned and left to roam the island freely. Their captivating presence and unique adaptation to the environment of the surrounding islands have made them a symbol of the island’s untamed spirit.

How to Get to Assateague Island National Seashore

You can get to the Assateague Island Nation Seashore through two different entrances. Once on the island, no road connects the entrances, so you must re-enter the mainland to access either. They include the north entrance, 8 miles south of Ocean City, MD, at the end of Route 611. And the south entrance, two miles east of Chincoteague, VA, is at the end of Route 175.
