What started out as an afternoon trek up the notoriously steep slopes of the Stirling Range turned into a rare Western Australian snow chase for two excited hikers earlier this week.

A blast of cold air from the Southern Ocean sent temperatures plummeting as it surged across southwestern Australia on Monday and Tuesday.

The wintry air mass arrived late on Monday, ushered in by a blustery cold front. By Tuesday, frigid winds and showers were spreading across the state's southwest and hail was falling in Perth.

But while most people were huddled inside trying to escape the characteristic bite of a Western Australia cold front, two hikers were heading straight for the coldest part of the state.

Cam Bostock, an Aussie adventurer and outdoor enthusiast, joined photographer Harry Rout on a hike up Bluff Knoll on Tuesday afternoon.

The pair knew from the forecast that snow was possible on the Bluff. But even as they made their way up the mountain, they weren't sure.

That is until they got high enough and got hit by a flurry of flakes.

Cam and Harry documented the snow chase in a video that captured their elation as they ascended to the rare sight of snow-covered ground in Western Australia.

Bluff Knoll typically sees at least one snowfall each year and can draw large crowds hoping to catch a glimpse of the rare spectacle.
