It was Bolton’s best result yet, and while a medal eluded him, to make the final four was an indication of his improvement this season.
In the opening round of 32, four Australian male snowboard athletes were in action, and while Bolton and Alex "Chumpy" Pullin made it through, Jarryd Hughes and Matthew Thomas did not proceed to the next round.
Bolton, who finished second in his heat, followed it up with a win in his quarter final to be the only one of the four to make it through to the semi-finals - the round of eight. Pullin finished third in his second race of the day to join the others on the sidelines.
In the women’s event, Belle Brockhoff, who had qualified fifth fastest, won her opening race in the round of 16. In the semi-finals she crossed the line third to go into the small final, where she in am impressive performance she won her final race of the day to finish fifth overall.
As the country's now sole survivor in the field, Bolton’s great form continued in the semi, where he finished second to Austrian Markus Schairer.
In the final four, which included two Austrians and a Russian, Bolton crossed the line in fourth place to produce the best result of his career, beating the tenth place from Sierra Nevada in Spain in 2013.
“I led the final until the last jump where I made a mistake while hunting for speed," Bolton said. "Hell of a day! Well done to all the riders."
Pullin finished the day in ninth place but was delighted for his fellow-rider Bolton.
"Wasn't the best day of racing for me at Montafon," Pullin wrote. "Won the whole shot in all my heats but got caught up with Nikolay taking an inside line in the last turn before the finish straight."
"So happy for my mate Cam Bolton who threw down four massive runs to just miss the win right at the line and place fourth."
