NASA's caption: the Rann of Kutch stretches inland in an almost straight line for 325 kilometres from the Arabian Sea coast; its marshy salt flats become snow white when the summer monsoon flood waters dry up; and the angular evaporation ponds along its floor are the heart of a major salt-producing industry. The straight lines are ditches that help control the flow of salt-rich water.

1The evaporation pondsFirst, the ponds. Twenty-two angular pans, maroon to rose to almost white, each walled by a thin bund.

2The drainage ditchesThen the straight lines. What are they? Ditches, steering the salt-rich water.

3The salt crustBetween them, the flat itself. A pale, mottled crust.

4The farmlandAt the corner, dark farmland. A grain of small fields.

5One line across it allAnd one straight line across it all, from the salt to the fields.
Rann Utsav, the festival at Dhordo on the white Rann, runs through the winter. Last season ran from 23 November 2025 to 20 February 2026; the dates for 2026 to 2027 were not yet published when this story was made.
