The Rann of Kutch is a vast area of salt desert / salt marsh located in the north-west of the Indian State of Gujrat. It borders the Arabian sea on the west, the Indus river delta to the north and stretches east for about 250 miles. It is split into the Great Rann and the Little Rann, somewhat loosely, based on ability to access and administer the vast region. It is arguably the largest salt desert / marshland in the world, covering an area of about 10,000 sq. miles. Desert or marshland?
