The toppling of a 200 million-year-old rock formation in Utah’s Goblin Valley State Park sparked outrage and disbelief, but it’s hardly the only instance of desecrating public treasures. Some 2,000 cases of vandalism occur in national parks each year, with perpetrators damaging ancient petroglyphs, hauling away artifacts and tagging cave walls and trees with graffiti.

On Tuesday at 12:15 p.m., Utah state parks director Fred Hayes, Joette Langianese of the group Friends of Arches and Canyonlands Parks, and Tribune justice editor Sheena McFarland join Jennifer Napier-Pearce to talk about the Goblin Valley case and vandalism in protected lands.
