Switzerland | Active public archive: 2021-present | Known for: Gazolina street skiing, Ovronnaz jib contests, Gazo2042 | Current public record: Gazolina-linked Swiss street skier
Leonard Siegenthaler is a Swiss freeski street and park skier whose verified public record is tied to Gazolina, Ovronnaz jib events, and the 2025 street video Gazo2042. He appears in regional Swiss freeski results rather than major FIS World Cup rankings, with Tour Freestyle Romand listings identifying him as Swiss, born in 2001, and connected to gazolina.exe. That places his profile in the crew-driven side of freeskiing, where rider lists, local contests, and street films carry more weight than formal international rankings.
At Ovronnaz Jib Night on December 30, 2021, Siegenthaler placed 12th in Adults M Ski, in a field that included Jeremy Boiston, Louis Coubes, Christian Moser, Max Pittet, Leo Rupp, Basile Genevay, Eliot Calvet, and others. Two years later, at the Tour Freestyle Romand Jib Freeski event in Ovronnaz on December 29, 2023, he placed 4th in Adults M with a 97.7 score, behind Remco Kayser, Aurélien Coubès, and Louis Coubes. The 2023 PDF lists his club/location as gazolina.exe, linking the contest record directly to the crew identity that appears in later street footage.
His clearest video marker is Gazo2042, released in November 2025 as Gazolina’s third street video and presented through Arsenic Anywhere. Downdays describes the project as a low-fi street video filmed around Norway, Switzerland, and the USA, with skiing by Leonard Siegenthaler, Thomas Gaudin, Basile Genevay, Albie Bigler, and Jesper Folkesson. That gives Siegenthaler a compact but specific public footprint: Swiss regional jib results, Gazolina crew affiliation, and street skiing documented across several countries.
