A Georgia man who parked on top of one of Yellowstone National Park’s thermal areas last fall has been ordered to serve a week in jail and stay out of the park for the next five years.

Yiyang Shen, a 25-year-old resident of Doraville, Georgia, received the sentence last month in Wyoming’s U.S. District Court.

The case started late on the night of Oct. 10, with a report that someone had parked in a thermal area near Biscuit Basin. Responding around 11:20 p.m., park rangers found a Honda SUV about 20 feet off the east side of the Grand Loop Road, near the trailhead for Artemisia Geyser.

The SUV had left visible tire tracks and a back tire was blocking a thermal stream, one of the rangers wrote in a probable cause statement obtained by the Tribune; footprints in the mud led away from the vehicle.

The Honda was unoccupied, but “while investigating, there were two males that came down the trail to the vehicle, both with white mud on their shoes.”

Shen was identified as the driver. He reportedly told the ranger that they couldn’t park outside of the white lines, “so we find it safer to park off the road.”

In response, “I explained why he should not be driving onto thermal features or walking in a thermal area,” the ranger recounted.

While a massive July eruption had closed Biscuit Basin and its typical parking area closed for the rest of last season, the law enforcement officer said there was space to park on the western shoulder. Assistant U.S. Attorney Ariel Calmes said the SUV’s tires caused “severe damage” to the thermal area that was not repairable or restorable.

Shen appeared remotely at the U.S. District Courtroom in Mammoth Hot Springs on March 13 and pleaded guilty to misdemeanor counts of operating a motor vehicle in a prohibited area and thermal trespass.

U.S. Magistrate Judge Stephanie Hambrick ordered Shen to serve seven days in jail, five years of unsupervised probation and pay $1,050. Beyond staying out of Yellowstone, Shen’s only other probationary term is to obey the law.

He wasn’t the only tourist to be sentenced for thermal trespassing last month: On March 19, Hambrick ordered a 44-year-old Seattle woman, Angela Flaherty, to serve a week in jail and pay $40 for venturing off the boardwalk near the Old Faithful Geyser. Flaherty reportedly walked 10 feet onto the geyser’s cone, with some of the Oct. 27 incident captured on video by a fellow visitor.

Both Shen and Flaherty have until September to serve their week-long jail stints and can do so at federal facilities that are “as close as possible” to their homes.

The two prosecutions were among a handful highlighted by the U.S. Attorney’s Office for the District of Wyoming in a March 24 news release.
