In addition to his work as an award-winning television writer and producer, Casey Schreiner has been a leading figure in the Los Angeles hiking scene since 2006, when he founded the site Modern Hiker. Since then, the site has grown to become the most-read hiking website on the West Coast, covering hundreds of trails from Canada to Mexico, breaking national news about public lands vandals, and offering in-depth reporting on outdoor issues facing the West.

On Modern Hiker, Schreiner broke the national news story of Casey Nocket’s social media posts documenting her 2014 vandalism spree of National Parks and Monuments across the West. This work documenting and contextualizing evidence on social media was instrumental in the Park Service’s case against Nocket.
