Holland Island was a marshy, rapidly eroding island in the Chesapeake Bay, in Dorchester County, Maryland, west of Salisbury. The island was once inhabited by watermen and farmers but has since been abandoned due to sinking of the land's surface associated with isostatic subsidence and sea level rise. It is located in the Holland Strait, between Bloodsworth Island and Smith Island, six miles west of Wenona, Maryland and Southeast of another former island, Long Island.
Holland Island was originally settled in the 1600s, taking its name from early colonist Daniel Holland, the original purchaser of the property from the Dorchester County Sheriff. By 1850, the first community of fishing and farming families developed on the island. By 1910, the island had about 360 residents, making it one of the largest inhabited islands in the Chesapeake Bay. The island community had 70 homes, stores and other buildings. It had its own post office, a two-room school with two teachers, a church, baseball team, community center, and a doctor. The islanders supported themselves mainly by dredging for oysters, fishing for shad and crabbing. Their fleet of workboats included 41 skipjacks, 10 schooners and 36 bugeyes, some of which were built on the island. [3] [4]
In 1914 the wind and tide began to seriously erode the west side of the island, where most of the houses were located. This forced the inhabitants to move to the mainland. Many disassembled their houses and other structures and took them to the mainland, predominantly Crisfield. Attempts to protect the island by building stone walls were unsuccessful. The last family left the island in 1918 when a tropical storm damaged the island's church. A few of the former residents continued living on the island during the fishing season until 1922 when the church was moved to Fairmount, Maryland. [3]
Stephen White, a minister, cared for the island for many years and formed The Holland Island Preservation Foundation. In June 2010, White sold the island to the Concorde Foundation. In October 2010, the last remaining house on Holland Island, built in 1888, collapsed. [4] [5]
The Holland Island Bar Light, a lighthouse originally built to the south of Holland Island in 1889, was dismantled and replaced with an automated light in 1960. [6]
The land of the island has been submerged as a result of erosion exacerbated by climate-change related sea level rise and associated with the sinking of the land's surface associated with isostatic subsidence. [7] [8] This process has caused a major loss of land on the island. Like other Chesapeake Bay islands, Holland Island is primarily made up of clay and silt. [4] The western ridge of the island is very exposed to waves in the bay, making it prone to erosion as well. The island's size was reduced by half, from approximately 160 acres (0.65 km2) in 1915 to 80 acres (0.32 km2) in 2005. [1]
Most of the remaining land on the island is now marsh, [3] but most of the time the entire island is underwater. Many birds, including terns, herons, songbirds, and pelicans used to be found on the island. A survey in 1995 counted 609 nesting pairs in a heron rookery on the island. Hurricane Isabel, a tropical storm by the time it reached Maryland in September 2003, destroyed 60 percent of the trees that previously served the rookery. [3] [9]
The Chesapeake Bay is the largest estuary in the United States. The Bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula, including parts of the Eastern Shore of Maryland, the Eastern Shore of Virginia, and the state of Delaware. The mouth of the Bay at its southern point is located between Cape Henry and Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the Bay's 64,299-square-mile (166,534 km2) drainage basin, which covers parts of six states, New York, Pennsylvania, Delaware, Maryland, Virginia, and West Virginia, and all of Washington, D.C.
The Delmarva Peninsula, or simply Delmarva, is a large peninsula and proposed state on the East Coast of the United States, occupied by the vast majority of the state of Delaware and parts of the Eastern Shore of Maryland and Eastern Shore of Virginia.
Smith Island is a collection of three distinct island communities – Tylerton, Rhodes Point, and Ewell, Maryland – on the Chesapeake Bay, on the border of Maryland and Virginia territorial waters in the United States. The island is the last inhabited island in Maryland that is not accessible by vehicle. Most of the islands are eroding due to tidal currents and sea level rise; a study conducted in 2008 by the DNR reported that Smith Island is expected to completely erode by 2100 if no action is taken.
Tangier is a town in Accomack County, Virginia, United States, on Tangier Island in the Chesapeake Bay. The population was 436 at the 2020 census. Since 1850, the island's landmass has been reduced by 67%. Under the mid-range sea level rise scenario, much of the remaining landmass is expected to be lost in the next 50 years and the town will likely need to be abandoned.
Subsidence is a general term for downward vertical movement of the Earth's surface, which can be caused by both natural processes and human activities. Subsidence involves little or no horizontal movement, which distinguishes it from slope movement.
Pelican Island National Wildlife Refuge is a United States National Wildlife Refuge (NWR), and part of the Everglades Headwaters NWR complex, located just off the western coast of North Hutchinson Island in the Indian River Lagoon east of Sebastian, Florida. The refuge consists of a 3-acre (12,000 m2) island that includes an additional 2.5 acres (10,000 m2) of surrounding water and is located off the east coast of Florida of the Indian River Lagoon. Established by an executive order of President Theodore Roosevelt on March 14, 1903, Pelican Island was the first National wildlife refuge in the United States. It was created to protect egrets and other birds from extinction through plume hunting. The oldest government wildlife refuge of any kind in North America is the Lake Merritt Bird Refuge in Oakland, California. Oakland Mayor Samuel Merritt declared it a wildlife refuge for migrating birds in 1869. In 1870, the state of California designated Lake Merritt a state game refuge.
The Eastern Shore of Maryland is a part of the U.S. state of Maryland that lies mostly on the east side of the Chesapeake Bay. Nine counties are normally included in the region. The Eastern Shore is part of the larger Delmarva Peninsula that Maryland shares with Delaware and Virginia.
The Choptank River is a major tributary of the Chesapeake Bay and the largest river on the Delmarva Peninsula. Running for 71 miles (114 km), it rises in Kent County, Delaware, runs through Caroline County, Maryland, and forms much of the border between Talbot County, Maryland, on the north, and Caroline County and Dorchester County on the east and south. It is located north of the Nanticoke River, and its mouth is located south of Eastern Bay. Cambridge, the county seat of Dorchester County, and Denton, the county seat of Caroline County, are located on its south shore.
Assateague Island is a 37-mile (60 km) long barrier island located off the eastern coast of the Delmarva Peninsula facing the Atlantic Ocean. The northern two-thirds of the island is in Maryland, and the southern third is in Virginia.
In geology, a forebulge is a flexural bulge in front as a result of a load on the lithosphere, often caused by tectonic interactions and glaciations. An example of forebulge can be seen in the Himalayan foreland basin, a result of the Indian-Eurasian (continent-continent) plate collision, in which the Indian plate subducted and the Eurasian plate created a large load on the lithosphere, leading to the Himalayas and the Ganges foreland basin.
Sinepuxent Bay Wildlife Management Area is a state wildlife management area (WMA) of Maryland that consists of several islands in Sinepuxent Bay, Isle of Wight Bay, and Chincoteague Bay in Worcester County.
Hoopers Island is a chain of islands in Dorchester County, Maryland, United States. Upper Hoopers Island and Lower Hoopers Island are surrounded by water with the Chesapeake Bay on the left side and the Honga River on the right side. The remote set of islands has much wildlife and is well known for sport fishing and crabbing industries. Hoopers Island was issued one of the earliest land grants in Dorchester County, Maryland.
St. Helena Island is situated between Round Bay and Little Round Bay in the Severn River, 5 miles (8.0 km) upstream from Annapolis, Maryland and 17 miles (27 km) south of Baltimore, Maryland.
Eastern Neck National Wildlife Refuge, a part of the Chesapeake Marshlands National Wildlife Refuge Complex, is a 2,286-acre (9.25 km2) island located at the confluence of the Chester River and the Chesapeake Bay. Established in 1962 as a sanctuary for migratory birds, Eastern Neck National Wildlife Refuge provides natural habitat for over 240 bird species — including bald eagles and transitory peregrine falcons — and is a major staging site for tundra swans.
Glenn Martin National Wildlife Refuge includes the northern half of Smith Island, which lies 11 miles (18 km) west of Crisfield, Maryland, and Watts Island, which is located between the eastern shore of Virginia and Tangier Island. Both islands are situated in the lower Chesapeake Bay.
In geology and geophysics, thermal subsidence is a mechanism of subsidence in which conductive cooling of the mantle thickens the lithosphere and causes it to decrease in elevation. This is because of thermal expansion: as mantle material cools and becomes part of the mechanically rigid lithosphere, it becomes denser than the surrounding material. Additional material added to the lithosphere thickens it and further causes a buoyant decrease in the elevation of the lithosphere. This creates accommodation space into which sediments can deposit, forming a sedimentary basin.
Nicolas Baudin Island is an island in the Australian state of South Australia about 500 metres west of Cape Blanche on the west coast of Eyre Peninsula about 25 kilometres south south-west of the town of Streaky Bay. The island is notable as a breeding site for Australian sea lions. The island has enjoyed protected area status since 2003 when it became part of the Nicolas Baudin Island Conservation Park.
The Tilghman Watermen's Museum records the maritime traditions of the people of Tilghman Island and the unique way of life of the watermen who lived on the island. It is located on Tilghman Island, Talbot County, Maryland, United States.
