Exclave

An exclave is a distinct geographical or geopolitical area which is part of a larger one, but is isolated from it by geographical or geopolitical boundaries, and thus is only accessible (by ground transportation) through the territory of a different area.^[1]

An example of an exclave is the small village of Kaskaskia, Illinois, which (due to the Mississippi River changing course in 1881) is accessible only by a small bridge from the neighboring state of Missouri.

It is possible for an exclave to also be an enclave (an area wholly surrounded by another). An example of a dual enclave-exclave is the city of Glendale, Colorado: it is an enclave (as it is wholly surrounded by Denver), but since Denver is a consolidated city-county, it is an exclave of neighboring Arapahoe County.
