Extract

The island of Sark lies 7 miles to the east of Guernsey. Its length from north to south is over 3 miles, and its average breadth is one and a half miles. The island is a table-land with an average height, above sea-level, of 300 feet, probably a result of marine planation of Pliocene date. Access is accomplished by scaling the cliffs of Havre Gosselin (west coast) or through the tunnel of Creux Harbour (east coast). The southern portion, Little Sark, joins the mainland by an isthmus 8 feet wide, 250 feet high, and 300 yards long, known as La Coup´ee. Here, as in many parts of the island, the cliffs drop sheer to the sea, and considerable care is required in examining the rocks.
