YELLOWSTONE NATIONAL PARK — Federal officials have charged members of a Canada-based group of men who post pictures of their travels on social media after the men were caught walking out to a hot spring where people are prohibited.

Yellowstone rangers filed a criminal complaint Monday against three members of the group known as High on Life SundayFundayz for stepping onto a geothermal feature. The men have been identified as Charles Ryker Gamble, Alexey Andriyovych Lyakh and Justis Cooper Price-Brown.

The National Park Service has the authority to enforce federal regulations that make it unlawful for anyone to travel off boardwalks or trails, according to the criminal complaint.

Authorities learned of the group’s actions Monday after a park visitor contacted Yellowstone officials to say he had seen the men leave the boardwalk, the complaint states. The visitor took photos and a video of the men Saturday while they were approaching the Grand Prismatic Spring and reaching into the spring.

Other people contacted the park to say they had seen photos posted on a Facebook page operated by High on Life SundayFundayz, according to the complaint. The group has removed many of the photos.
