John Robinson, known as JahCork, is a street and park skier and video editor associated with Michigan's freestyle skiing scene. In 2020, he skied, filmed and edited DRUWAVE II, a project filmed at Mt. Brighton and Pine Knob between January and March. The production featured Drew Mack, Aidan Abood, Parker Weston, Liam Cassidy and other members of the Brighton Air Cadets crew. Robinson also edited a Pine Knob opening-day video in December 2020, appearing alongside several of the same Michigan skiers.

In 2021, Robinson continued his filming and editing work with DRUWAVE III, featuring Jordan Stuart, Parker Weston, Drew Mack and Hagen Brown. His 2022 project JAHSTREET followed his first season filming street skiing in Utah and Michigan, with support from Noah Rodarte, Luke O'Brien and OS Crew. That year, Robinson was also credited as a skier in ELECTRIC, an OS Crew production filmed across several western American states.

In March 2024, Robinson participated in B-Dog Off The Leash at Wild Mountain, Minnesota. A photograph from the event shows him skiing a down-flat-down rail alongside Jack Kaiser. In 2025, Robinson released SNOWMAN, a collection of ski footage recorded between 2022 and 2024, with filming contributions from Ben Haley, Antonio Acevedo, Hayden Benninghofen and other collaborators.
