Bluff Knoll, Mountain summit in Stirling Range National Park, Australia

Bluff Knoll is the highest peak of the Stirling Range, rising 1,099 metres with a 650-metre prominence. Its upper part is bare pale grey and tan stone, split by vertical fissures into blocky buttresses; below, steep furrowed ridges of dark green and brown vegetation fall away into shadowed gullies. The crest runs roughly level, dips near the centre and rises again toward a lower top on the right.

The mountain formed during Australia's separation from Antarctica, with sedimentary rocks dating back approximately 1.2 billion years. These rock layers accumulated from deposits left by an ancient shallow sea that once covered the region.

The Mineng and Koreng/Goreng groups of the Noongar Nation call the peak Boola Miyel or Pualaar Miial, 'great many-faced hill' or 'many eyes', after rock formations that resemble eyes looking across the valley. Elders Jack Williams and Averil Dean say the spirit Noyintj lives there and that Noongar spirits return to Boola Miyel before passing on. Signage at the carpark names a mist-like spirit, Noatch.

The walking trail covers about 6 kilometers and takes three to four hours, with steep and demanding sections requiring sure footing and preparation. Visitors should bring weather-resistant clothing, as conditions change quickly and strong winds are common at the top.

The summit ranks among the coldest locations in Western Australia and remains one of the few spots in the state where winter snow falls regularly. This rare weather experience makes it a special destination even during the colder months.
