Five defendants from the Canadian group High On Life appeared Tuesday, November 1, before U.S. Magistrate Judge Mark Carman at the Yellowstone Justice Center in Mammoth Hot Springs, WY. Hamish Cross and Parker Heuser pleaded guilty to violations in Yellowstone National Park and Death Valley National Park. The remaining three defendants from High on Life pleaded not guilty and will be appointed court attorneys.  

The group, consisting of Charles Ryker Gamble, Alexey Andriyovych Lyakh, Justis Cooper Price Brown, Parker Heuser, and Hamish McNab Campbell Cross, were the subject of multiple investigations by the National Park Service and the Bureau of Land Management.

H. Cross pleaded guilty to charges in Yellowstone National Park that included disorderly conduct by creating a hazardous condition and foot travel in a thermal area. He agreed to pay over $8,000.00 in fines, restitution, community service payments paid to Yellowstone Forever, and fees. P. Heuser pleaded guilty to two violations in Death Valley National Park that included riding a bike in wilderness and commercial photographs without a permit. He will also pay for collateral fines that stemmed from violations at the Bonneville Salt Flats (BLM). He agreed to pay more than $1,000.00 in fines and fees. P. Heuser was not charged any violations in Yellowstone National Park. Both individuals will be on probation for five years which includes being banned from public lands managed by the U.S. Department of Interior, U.S. Department of Agriculture, and the U.S. Army Corps of Engineers.

On May 16, 2016, a concerned citizen contacted park rangers in Yellowstone National Park, after seeing four individuals walking on Grand Prismatic Spring. During the course of the investigation, park rangers identified the four individuals involved in the violations in Yellowstone National Park and arrest warrants were issued. Through the use of social media and tips from the public, additional investigations were conducted about the group’s activities on other federal lands.

The High on Life group was issued violation notices from:

“The judge’s decision today sends a very clear message about thermal feature protection and safety,” said Yellowstone National Park Superintendent Dan Wenk. “Hamish Cross’s egregious actions damaged a world-class hot spring and risked his own life coupled with the lives of responding rangers. We look forward to the outcome of the case regarding the three remaining defendants.”                                                   

Harm can be done by walking on bacterial mats that surround thermal features like Grand Prismatic Spring. The colorful mats contain communities of thermophiles, or heat-loving organisms. Walking on the mats damages the microscopic communities and the footprints left behind impact the visual landscape people expect in Yellowstone.

Scalding water also underlies much of the thin, breakable crust around hot springs like Grand Prismatic Spring. Many hot springs are near or above the boiling point and can cause severe or fatal burns. More people have been injured or killed in hot springs than any other natural feature in Yellowstone. For example, a fatality occurred in June, 2016, at the Norris Geyser Basin when a man walked off the designated boardwalk, slipped, and fell into a hot spring.

Take the Yellowstone Pledge. Protect your park and protect yourselves by staying on the boardwalks. If you witness resource violations, call 911 or contact a park ranger.
