If you want to drive from the small coastal town of Point Roberts to its own county seat in Blaine, Washington, you must buckle up, exit the United States, clear Canadian border control in Tsawwassen, drive 25 miles through British Columbia, and re-enter the United States through the Peace Arch port of entry.
How The Treaty of 1846 Created a Geopolitical Island
In June 1846, the United Kingdom and the United States signed the Oregon Treaty, resolving decades of joint territorial disputes by extending the international boundary along the 49th parallel from the Rocky Mountains westward straight through the Strait of Georgia to the Pacific Ocean.
The negotiators possessed imperfect maps and failed to notice that a tiny, 4.88-square-mile thumb of land called the Tsawwassen Peninsula jutted downward just south of the 49th parallel. By strictly slicing across the line, Britain inadvertently ceded the southernmost tip of the peninsula to the United States.
The 4-Border School Commute
Because Point Roberts only maintains a primary school up to the 4th grade, middle and high school students must board a dedicated yellow school bus every weekday morning. The bus crosses the Canadian border at Tyee Drive, travels through Delta, B.C., crosses back into the USA at Blaine, and repeats the exact reverse journey every afternoon—racking up four international customs clearances every school day.
Daily Life in a Pene-Exclave
A pene-exclave is defined as an area of territory that is geographically part of the mainland of one state, but can only be practically reached by land through the territory of another state. Point Roberts is one of the most prominent examples on earth.
The town's permanent population hovers around 1,100 residents. The local economy relies heavily on Canadian visitors seeking cheaper American parcel shipping depots, duty-free gasoline, dairy products, and alcohol. During the pandemic border closures from 2020 to 2022, Point Roberts was effectively quarantined from its own mother country, requiring emergency municipal ferries to transport groceries and medical supplies from Bellingham.
Key Infrastructural Oddities:
- Telephony & Dialing: Point Roberts belongs to Washington area code 360, but calls from nearby Vancouver (just 20 miles north) are classified as international overseas calls.
- Emergency Services: While Point Roberts has its own volunteer fire department and EMTs, serious trauma cases require air evacuation by helicopter to Saint Joseph Hospital in Bellingham, as crossing through Canadian checkpoints with an active patient involves complicated customs procedures.
- Water & Utilities: Water is purchased from the Greater Vancouver Water District in Canada and piped south across the international border into American pipes.
