Though Uluru is the largest "free-standing" monolith, Mount Augustus
is the world's largest monolith. Located 320 km east of Carnarvon in
Western Australia, it is 2.5 times larger than Uluru (Ayers Rock). One
of the most spectacular solitary peaks in the world, standing at 1105
metres above sea level, Its summit has a small peak on a plateau, and
rises about 717 metres above a stony, red sandplain of arid shrubland
dominated by wattles, cassias and eremophilas. The rock is 8 km long
and covers an area of 4795 hectares.
Because of its immense size, the mountain is clearly visible from
the air for more than 160 kilometres. It is made of sedimentary rocks,
Upper Proterozoic sandstone and conglomerate which, according to
geologists, was originally deposited on an ancient sea floor about 1
000 million years ago, then later folded and uplifted. The rock has a
variety of colours, ranging from purple, to pink, orange and red.
The Summit Track begins at Beedoboondu car park and is a 12km return
walk. Just into the walk at a place called Flintstone Rock there is a
rock slab with Aboriginal engravings under it.
Kotka Gorge Trail
An easier walk than the summit trail, this is the closest walk to
the Mount Augustus Resort (camping ground) only a short drive. The
Kotka Gorge Trail begins at Warrarla.
