In this work, Sabrina Robertson Nangala depicts the sacred site of Pirlinyarnu, 165 km west of Yuendumu, to which the Dreaming (Jukurrpa) of Water (Ngapa) is linked.

Legend has it that in the Dreamtime - the mythical time of creation for the Aborigines - two rainmaking ancestors from the Jangala family called for rain with their songs, triggering a huge storm. This storm mixed with another and moved along various clan territories. It was then seized by a brown hawk ancestor (kirrkarlanji) who let it fall on Pirlinyarnu, where a very large marsh (maluri) formed. This marsh still exists today and when it rains, hundreds of ducks (ngapangarla) gather there.

The very fine lines that enclose the dotted lines form rectangles that, for the Warlpiri - the artist's family group - symbolise the cumulus and stratocumulus clouds that appeared in the sky before the mythical storm. They are part of a series of dots symbolising the flow of rivers that formed as a result of the torrential rains.
