Prince Patrick Island is the most westernly of the Queen Elizabeth Islands in Northwest Territories, Canada. The area of the island is estimated at 15,848 kmē. The island is icelocked year-round, making it one of the most inaccessible parts of Canada.
Prince Patrick Island is uninhabited and there are no known communities, past or present. A station called Mould Bay was opened in 1948 as part of a joint Canada-U.S. military effort to support a high arctic weather station network. It had a temporary staff of between 10 and 40 people. The station was closed in 1995 due to budget cuts and replaced with an automated weather station. The remains of the buildings still stand.
Prince Patrick Island was first explored in 1853 and (much later) named for Prince Arthur William Patrick, Duke of Connaught, who was Governor General 1911-16.
The island rises to only about 200m, and the area is seismically active.
