Pierce Brosnan has to cough up some cash after posting photos of himself standing on off-limits thermal areas of Yellowstone National Park last year. The actor was fined $500 and must pay $1,000 to the Yellowstone Forever Geological Fund, according to the U.S. Attorney’s Office, District of Wyoming. Brosnan, who was cited in the case in December, pleaded guilty to foot travel in a thermal area, the U.S. Attorney’s Office said. In November, Brosnan posted pictures of himself to Instagram standing on a Yellowstone National Park thermal feature at Mammoth Hot Springs. The National Park Service (NPS) investigated, and the case was prosecuted by Assistant U.S. Attorney Ariel Calmes, who asked the court to sentence Brosnan to two years’ probation and the maximum $5,000 fine.
