A steel filter, tonnes of rock, a digger and colossal track tires might not seem the ultimate plaything.
But three world-class wakeboarders turned such objects into the ultimate wakeboard experience inside a disused quarry in Carinthia, Austria.
"Falling Rocks" follows the new voyage of X Games medallists and wakeboarders Dominik Hernler, Felix Georgii, and Parks Bonifay.
Pulled by a winch, it was a return to his roots for Hernler, who persuaded his peers to join him on the quarry quest.
They only used the objects available on site - a 1.5-tonne stone filter made of steel, which was turned into a kicker, as well as steel pipes for rails and drainage pipes, a digger, vast tires and metal sheets over the course of two weeks.
A Complex Operation
Among the stand-out stunts was Hernler using a four-meter-high digger bucket to put a cab 270 front boardslide into his run.
"For me, the 'Falling Rocks' project was something very special as it took place practically around the corner from my home," said Hernler said.
"Finally, we didn't have a road trip in which we had to spend endless miles in the car, but we could get to grips with one specific spot. It particularly pleased me that so many friends from home were there to help. It was awesome to have Parks and Felix there."
"When Dominik and Sam showed me the quarry for the first time, I was overwhelmed," added Georgii.
The vertical wall with its white, sharp rocky edges combined with the crystal-clear water looks awesome and offers everything for a perfect wakeboard set-up."
Previous eye-catching wakeboard experiences from Hernler have included the hydropower plants of Upper and Lower Austria, and a trip through Paris' waterways.
