Lake Disappointment, or Kumpupintil/Kumpupirntily[1] in the Western Desert Language, is an endorheic salt lake located in the Pilbara region of Western Australia.

Description

The 33,000-hectare (82,000-acre) lake typically is dry except during very wet periods such as the 1900 floods and in many recent tropical wet seasons since 1967. It lies on the Tropic of Capricorn, due east of the mining town of Template:WAcity and the Template:WAcity. It is at the northern side of the Little Sandy Desert and south of the Karlamilyi National Park. The Canning Stock Route passes down the western shores of the lake and the surrounds consist mostly of sand dunes. Its elevation is 325 metres (1066ft) above mean sea level.[2]

Mythology

In indigenous culture, Kumpupintil was off-limits to the tribes neighbouring the area, such as the Kurajarra, Wanman, Kartudjara and the Putidjara. The reason for the taboo, existing down to modern times, derives from the lake's mythological associations with the Ngayurnangalku spirits thought to live below its surface. This prohibition extended to flying over the area, since the Ngayurnangalku, ancestral cannibal beings with pointy teeth and clawlike fingernails,[3] are deemed capable of ripping even planes that intrude over the lake's airspace.[4]

The lake is home to many species of water birds.[5]

The discovery of a new species of dragon lizard, Ctenophorus nguyarna, at the site was announced in 2007.[6][7]

Name

Lake Disappointment was named by the explorer Frank Hann in 1897.[8] Hann was in the area exploring the east Pilbara, around Rudall River. He noticed creeks in the area flowed inland, and followed them, expecting to find a large fresh water lake. The lake was typically dry and so was named Lake Disappointment.[lower-alpha 1]

Notes

  1. "It was left to Frank Hann in the course of an exploring/prospecting expedition travelling east from Nullagine to sight and name the lake on 20 April 1897. Hann had travelled from Nullagine across the Davis River to the Coolbro Creek, then to the southeast following and naming the Broadhurst Range, crossing the upper Rudall River and the Cotton Creek as far as the Harbutt Range where he turned south to the Mckay Range. Here to the southward he sighted a large lake ten miles distant, and they made their way to it next day, but 'found it was all white salt ... it is the largest thing in lakes I ever saw ... I shall call the lake Lake Disappointment as I was disappointed in not finding water in it."[9]
