Пойнт-Робертс: Эксклав на границе США и Канады.

Point Roberts is a pene exclave of Washington on the southernmost tip of the Tsawwassen peninsula, south of Vancouver, British Columbia. The area, which had a population of 1,191 at the 2020 census, is reached from the rest of the United States by traveling 25 mile (40 km) through Canada, or by boat or private airplane. It is a census designated place in Whatcom County, Washington, with a post office, and a ZIP Code of 98281. Direct sea and air connections with the rest of the U. S. are available across Boundary Bay. Point Roberts was created when the United Kingdom and the United States settled the Pacific Northwest American Canadian border dispute in the mid 19th century with the Oregon Treaty. The first Europeans to see Point Roberts were members of the 1791 expedition of Francisco de Eliza. The maps produced from Eliza's explorations depicted Point Roberts as "Isla de Cepeda" or "Isla de Zepeda." In 1792, the British expedition of George Vancouver and the Spanish expedition of Dionisio Alcalá Galiano encountered one another near Point Roberts. In the morning of June 13, 1792, the two ships under Galiano sailed into Boundary Bay and verified Point Roberts was not an island, which was thus renamed Punta Cepeda. They then sailed around Point Roberts and immediately encountered HMS Chatham, the second ship of Vancouver's expedition. The two parties made contact and agreed to share information and work together in mapping the Strait of Georgia. Point Roberts acquired its present name from George Vancouver, who named it after his friend Henry Roberts, who had originally been given command of the expedition. Point Roberts assumed its present political status in 1846, when the Oregon Treaty extended the 49th parallel as the boundary between U. S. and British territory from the Rocky Mountains to Georgia Strait.

After years of joint occupation of the disputed area between Mexican California and Russian America known as the Oregon Country to the Americans, and as the Columbia District to the British, American expansionists like U. S. Senator Edward A. Hannegan of Indiana urged U. S. President James K. Polk to annex the entire Oregon Country up to latitude 54°40′N, as the Democrats had been elected on the slogan "Fifty Four Forty or Fight". While his government asserted that the title of the United States of America to the entire territory was unquestionable even though there was only one U. S. resident (a former Briton) north of the Columbia basin, Polk and Secretary of State James Buchanan made an offer of a boundary at 49 degrees with the line straight across Vancouver Island, with no commercial privilege to be granted to the British south of the line, with the exception of free ports on Vancouver Island. The British rejected the offer and the U. S. soon withdrew it. On April 18, 1846, notice was forwarded to London that the U. S. Congress had adopted a joint resolution abrogating the Treaty of 1818 which provided for joint occupancy. The British emissary, Richard Pakenham, had been advised that the last concession he could expect of the United States was to bend the boundary at the 49th parallel around the southern end of Vancouver Island. Fort Victoria was viewed as the future center for settlements on the island. It was deemed necessary around this point in time to give up territory on the Lower Mainland to keep Vancouver Island part of British North America. Lord Aberdeen, British Foreign Secretary, proposed a treaty making the 49th parallel the boundary to the sea, giving the UK the whole of Vancouver Island. The Treaty of Oregon was concluded on June 15, 1846. The acceptance of the 49th parallel as the international boundary was concluded without precise knowledge of its effects. Later, as the Boundary Commission surveyed the line, the British government realized the peninsula of Point Roberts would be an isolated part of the United States. The British Foreign Office instructed Captain James Prevost, the British Boundary Commissioner, to inform his U. S. counterpart of the situation and request Point Roberts be left to Britain, because of the great inconvenience it would be to the United States. If the American Boundary Commission was reluctant, Prevost was instructed to offer "some equivalent compensation by a slight alteration of the Line of Boundary on the Mainland". It is not known how the U. S. commissioner responded, but Point Roberts remained part of the United States.

During the 1858 Fraser gold rush, prospectors from Victoria, BC who were attempting to avoid tax collection briefly settled Point Roberts. Their settlement was called Robert's Town and consisted of six wooden buildings, including a store and saloon, but lasted less than a year. In 1949, there was talk about Point Roberts seceding from the U. S. and joining Canada. A regional development plan for the Lower Mainland presented in 1952 suggested turning Point Roberts into an international park or leasing it for 99 or 999 years. In 1973, a drought that caused the wells to run dry created tensions between Point Roberts's U. S. and Canadian residents. The Americans threatened to cut off the Canadian residents' water supply — and hung up signs saying "Canadians Go Home" — unless the Canadian municipality of Delta agreed to provide water. An agreement signed on August 28, 1987, requires the Point Roberts Water District to purchase raw water on an annual basis from the Greater Vancouver Water District. Delta Fire Department also provides assistance to the Point Roberts volunteer fire department when requested. Until 1988, BC Tel (now Telus) provided telephone service; the sole exchange prefix of 945, officially part of area code 206, could also be dialed through area code 604 during the period of BC Tel ownership. After the September 11 attacks of 2001, security at border crossings—including Point Roberts—was increased, leading to long delays for residents. The Canadian border was closed to non essential travel in March 2020 due to the COVID 19 pandemic, which had been worsening in both countries but especially in the United States. In 2020, a study found that Point Roberts had lost 80 percent of its business and hundreds of seasonal residents as a result of the pandemic and border shutdown. The area, described as a "ghost town" by the local chamber of commerce director, had no confirmed cases of COVID 19 as of September 2020. A temporary ferry was set up by the Port of Bellingham in August 2020 to connect Point Roberts to the mainland, initially to Blaine and later to Bellingham. The border was fully reopened for non essential travel in August 2021 and the ferry service ceased the same month. During the COVID 19 pandemic, Point Roberts was acclaimed as the "safest place" for avoiding coronavirus due to its isolation from the mainland United States and Canada and very low case numbers. Because of limited access to the rest of Whatcom County and border closures into Canada, the case numbers remained very low.

Point Roberts is a U. S. exclave bordered by Canada and the waters of Boundary Bay. It is 22 mile (35 km) south of Downtown Vancouver, British Columbia. Point Roberts is part of the U. S. because it lies south of the 49th parallel, which constitutes the Canada–US border in that area. Other exclaves of this type include parts of Minnesota such as the Northwest Angle and Elm Point, Minnesota. Alburgh, Vermont and nearby Province Point are separated from the rest of the U. S. by Lake Champlain, though Alburgh is reachable by highway bridge from "mainland" Vermont. Point Roberts borders the municipality of Delta in British Columbia. Boundary Bay lies to the east of Point Roberts and the Strait of Georgia to the south and west. The U. S. portion of the peninsula is about 2 mile (3 km) from north to south and about 3 mile (5 km) from east to west. It has an area of 4.884 square miles (13 km2), all land.

Beneath Point Roberts, the bedrock of the Chuckanut Formation was deposited as an alluvial plain containing layers of sediments consisting of silt, sand, gravel and peat. During the last 60 million years the sediments were compacted and folded by mountain building forces from continental drift to form strata of siltstone, sandstone, conglomerate and coal. During recent geologic history, the Chuckanut formation was overridden by four or more glaciations. Point Roberts consists of a series of the resulting glacial sediments resting upon the Chuckanut Formation. The lowest glacial sediments (now near sea level) are from Salmon Springs or older glaciations. At the peak of the most recent glaciation, the main ice sheet was in excess of 7000 feet (2134 m) thick as it moved southward between Vancouver Island and the Canadian Coast Range and down the Strait of Georgia. A smaller lobe of the continental glacier in excess of 5000 feet (1524 m) traveled down the Fraser River flood plains merging with the main ice sheet over the greater Vancouver area and Whatcom and Skagit Counties. The coalesced continental ice sheet traveled south terminating in the vicinity of Chehalis, Washington. Relatively impermeable Vashon glacial lodgment till (estimated to be as much as 40 feet (12 m) thick at the uppermost layer) was plastered over the advance outwash as the weight of the 7000 feet (2134 m) thick plus Strait of Georgia ice lobe moved southward over approximately 10,000 years. (Armstrong, et al., 1965) Point Roberts, Tsawwassen, and part of British Columbia extending past English Bluff comprised an island at the close of the Vashon Glaciation, approximately 11,000 years ago. As the ice sheets melted, the thinner Fraser Lobe began to float while the Strait of Georgia lobe acted as a dam forming a lake under the Fraser Lobe. Sediments settling from the melting, floating ice resulted in the accumulation of 300 feet (91 m) or more of glacial marine drift over much of western Whatcom County. (Easterbrook, 1976; Geologic Map of Western Whatcom County, Washington, USGS, Map I 854 B) This glacial marine drift is generally soft and was not consolidated by the weight of the glacier. A discontinuous, thin mantle of this glacial marine drift above the glacial lodgement till has been identified sporadically across Point Roberts. The uppermost layer of glacial sediments consists of recessional sand, silt, and gravel deposited as the Strait of Georgia ice lobe receded. Since the recession of the glaciers, the Fraser River has deposited deltaic sediments on the north and easterly side of the Point Roberts Tsawwassen Island, connecting it to the Greater Vancouver mainland (approximately 2,500 years ago, Murray 2008). At some locations, these sediments have been eroded or removed, exposing the lodgement till.

Despite its proximity to 49 °N latitude, Point Roberts has an Oceanic climate (Köppen: Cfb) although winters may be colder for this climatic subtype, similar to the Vancouver Seattle Portland axis. Point Roberts lies within a depression created by Vancouver Island, the north shore mountains surrounding Vancouver, and the North Cascades (including Mount Baker). This micro climate provides some of the mildest weather in the Pacific Northwest. With annual precipitation of about , Point Roberts enjoys more sunny days and a milder climate than its neighbors. While 49 °N latitude suggests a harsh winter, snow averages and low January temperatures are milder than the American average: in vs and vs , respectively. Although the amount of rainfall is less than the regional average, it is better distributed through the year , with 146 days of precipitation. The comfort index is high.

As of the 2010 United States Census, The local post office and several private companies rent many post office boxes to individuals and businesses from the Greater Vancouver area, who find it a convenient and fast way to receive mail and parcels from the United States without paying for cross border shipping costs, or as a delivery point for online chases when American sellers do not ship outside the U. S. but it has since changed to using one in Blaine, directly on the border. Because entry to Point Roberts from the rest of the U. S. requires two international border crossings, it has sometimes been described as "the best gated community in the U. S." Popular folklore describes the town as a popular resettlement site for the US Federal Witness Protection Program, assisting informants who testify against criminals to relocate under new identities for their protection.

Point Roberts Primary School, the only school in the exclave, provides only kindergarten and first, second and third grades and is part of the Blaine School District. It is the smallest school in Whatcom County, with approximately 15 students and one full time teacher, and is classified as a remote and necessary school by the state government. The three room schoolhouse opened in 1993 and began offering third grade lessons in 1999. From 4th grade onward, American children must take a 40 minute ride through British Columbia, crossing back into the United States at Blaine, Washington. Canadian children can attend school in Delta, British Columbia.

The only authorized land access to Canada from Point Roberts is Point Roberts Boundary Bay Border Crossing, the westernmost in the Lower 48. On the US side, this major thoroughfare northward is named Tyee Drive; on the Canadian side, it is 56th Street. Point Roberts also has a small airport (Point Roberts Airpark) and a large marina (Point Roberts Marina Resort) for air and water access; these two point facilities allow direct access to the rest of Washington state without the need to enter Canada. It was initially run once per week, but the frequency was increased to twice a week and the ferry was diverted to serve the Bellingham Cruise Terminal due to high demand. Ferry service ended in August 2021.

Until 1988, Point Roberts telephone numbers were in British Columbia's area code 604 and served by BCTel, the local telephone company for most of British Columbia. It was served by the 945 exchange which was officially in area code 206, the area code for most of western Washington, but protected in 604, resulting in the oddity of calls from British Columbia being local calls while calls from Washington and the rest of the United States were billed as international calls. In 1988, Point Roberts service was severed from BC Tel, and the protection of the 604 945 prefix ended, at the expense of losing the ability to make local calls to any other exchange in either country. Along with the rest of Whatcom County, Point Roberts moved to area code 360 in 1995. The local regular service telecom provider is Whidbey Telecom. Although Point Roberts is nominally part of the Seattle television market, the only over the air stations available in the town come from the Metro Vancouver region and Bellingham, Washington. Cable television in Point Roberts was provided by Delta Cable, a subsidiary of Canadian cable company EastLink. Delta Cable pulled out of Point Roberts with short notice in August 2019. Whidbey Telecom is the broadband Internet provider to residents of Point Roberts. In 2019, Whidbey Telecom began construction to provide fiber optic Internet to Point Roberts. Mobile telephone service is provided by a variety of companies, both American and Canadian.
