The Isle of Man and the Solway Firth54.2N 4.5W
The Isle of Man (bottom) is a self-governing Crown dependency, located in the Irish Sea at the geographical centre of the British Isles. The island is not part of the United Kingdom (nor of the European Union) but foreign relations, defence, and ultimate good-governance of the Isle of Man are the responsibility of the government of the United Kingdom.
Approximately 32 miles (51 km) long and between 8 miles (13 km) and 15 miles (24 km) wide, the island has an area of around 221 square miles (570 km2).
In the Irish Sea northeast of the Isle of Man is the Solway Firth, a firth (large sea bay) that forms part of the border between England and Scotland. The coastline of the Solway Firth is characterised by lowland hills and small mountains.
The firth’s water itself is generally benign with no notable hazards except some large areas of salt and mud flats which often contain dangerous patches of quicksand that move on a regular basis. Here, its upper reaches appear dark brown from mud flats and from sediments flowing into the firth from the River Waver and the River Wampool.
