Cool footage of a four-year-old snowboarder hitting box slides, rails, jumps and cliffs on a mountain in Utah, USA.

The video, filmed at Snowbird by the boy's father over Spring Break this year, shows little Terje taking to the slopes for his third season and performing a series of tricks.

His mother later wrote online: "Terje also loves to skateboard and has been taking karate to help his focus.

"He has been on a board since he could walk and his skills show it."

"When we go up we just kind of have fun; he likes to do it," she continued.

"His father points out little things that he can do and he just goes for it."

Tiny snowboarder can really shred! This will be Terje’s third season on a snowboard. He has really progressed this year and can ride anywhere on the mountain. In the video you will see him hit box slides, rails, jumps, and cliffs. There is also a wipeout section! Really impressive for a 4 year old who won’t turn 5 until December 20th.
