Three of the four Canadian filmmakers who were caught roaming onto Yellowstone's Grand Prismatic hot spring have pled not guilty to charges of foot travel in a thermal area and disorderly conduct. Hamish McNab Campbell Cross was the only member of the group representing clothing brand High on Life to plead guilty to his charges. He'll pay a fine of $8000 and accepts a five year unsupervised probation.

The remaining three have received court-appointed lawyers and may face a bench trial if they do not accept plea deals. The Jackson Hole News and Guide reports that the group's previous attorney, who removed himself from the case due to a conflict of interest, mentioned that the US Attorney is considering jail time.

The Grand Prismatic incident is just one of quite a few recent cases park vandalism. Stiffer penalties for offenders may help reduce incidences of vandalism, but is an $8000 fine enough? Do the filmmakers pleading not guilty deserve jail time? Tell us what you think in the comments.
