SALT LAKE CITY — A series of colorful, eerie faces painted on rocks in some of the West's most famously picturesque landscapes has sparked an investigation by the National Park Service and a furor online.
Agents so far have confirmed the images in Yosemite and four other national parks in California, Utah and Oregon. Park Service spokesman Jeffrey Olson said the vandalism could lead to felony charges for the person responsible.
The images appear to come from a New York state woman traveling across the West this summer and documenting her work on Instagram and Tumblr, said Casey Schreiner of modernhiker.com, whose blog post tipped off authorities.
The investigation is the subject of well-trafficked threads on the website Reddit, where people railed against the drawings as the defacing of irreplaceable natural landscapes.
"You're seeing this emotional response of people who feel like they've been kicked in the gut," Schreiner said.
It's not the first time vandalism in parks has been documented on social media. Last year in Utah, two Boy Scout leaders caused an online uproar when they recorded themselves toppling an ancient rock formation at Goblin Valley State Park and posted it on YouTube.
But in this case, the woman appears to consider the work an artistic expression, Schreiner said.
One photograph online showed a painting of a woman's face on a rock outcropping against the panoramic sweep of Oregon's Crater Lake National Park. In another, a backpack-size line drawing of a woman smoking a cigarette appears on red rock in Utah's Zion.
