It is located in the Hamersley Range within the southeastern part of Karijini National Park in the Pilbara region, approximately 86 kilometres (53 mi) south-southeast of Wittenoom,[4] and 87 kilometres (54 mi) east-southeast of Tom Price.

Tom Meharry directed the survey party and performed the calculations that confirmed the mountain was the highest peak in Western Australia, being 15 metres (49 ft) higher than Mount Bruce which lies 62 kilometres (39 mi) northwest of Mount Meharry.

The Minister for Lands Stewart Bovell approved this on 28 July 1967 and a notice naming the peak was published in the Western Australian Government Gazette on 15 September 1967.

In 1999, Gina Rinehart, daughter of Lang Hancock, applied to the Geographic Names Committee to rename the mountain after her father.

In dry conditions, a two-wheel-drive vehicle can reach the national park boundary at about 800 metres (2,600 ft) elevation, requiring a walk of about 7 kilometres (4.3 mi) to the summit.
