A man is free after being stuck between two boulders at Mt Arapiles for almost 10 hours overnight.
A 24 year old man became stuck while negotiating the Mt Arapiles squeeze test at around 10pm.
SES, the CFA, Ambulance Victoria and Victoria police units assisted with the rescue.
Crews from as far away as Ballarat were called to the rescue.
Giant heaters were brought in to help keep the man warm but police said he was in a life threatening condition due to "crush" syndrome.
This isn't the first time the "squeeze test" has claimed an adventurer's freedom.
In 2011, a Melbourne teenager was rescued at Mount Arapiles after becoming stuck in the rock crevice.
The boy, 15, was on a school trip with Donvale Christian College when he decided to squeeze through a crack in the boulder in what is commonly known among climbers as 'The Squeeze Test'.
Natimuk climber Gareth Llewellin said he also attended the scene and helped with the rescue efforts.
"If you are not a climber it's a strange thing to hear about, but the Squeeze Test is something that's commonly done," Mr Llewellin said at the time.
