About
Mount Oxley (Aboriginal: Oombi Oombi) is a hill situated 32 kilometres (20 mi) from Bourke in the Far West region of New South Wales in outback Australia.
The hill appears as a mesa-like inselberg, rising 150 metres (490 ft) above the Western Plains. It is a small relic of a formerly large sedimentary rock formation, mostly now eroded away. The underlying and surrounding rocks are sedimentary sandstone and metamorphic quartzite.
The first European to visit the mountain was Charles Sturt in December 1828. He mentioned "a report as of a gun discharge" near Mount Oxley. He surmised "it might be some gaseous explosion".
