Sir Creek
Sir Creek 
listen is a 96 km (60 mi) tidal estuary on the border of India and Pakistan. The creek, which opens up into the Arabian Sea, divides the Gujarat state of India from the Sindh province of Pakistan. It is located at approximately 23°58′N 68°48′E / 23.967°N 68.800°E.
The long-standing dispute hinges in the actual demarcation "from the mouth of Sir Creek to the top of Sir Creek, and from the top of Sir Creek eastward to a point on the line designated on the Western Terminus". From this point onwards, the boundary is unambiguously fixed as defined by the Tribunal Award of 1968.
The creek itself is located in uninhabited marshland. During the monsoon season between June and September, the creek floods its banks and envelops the low-lying salty mudflats around it. During the winter season, the area is home to flamingoes and other migratory birds.
The dispute lies in the interpretation of the maritime boundary line between Pakistan and India. Before independence, the area was part of British India. After independence in 1947, Sindh became a part of Pakistan while Gujarat remained a part of India.
