Officials at Yosemite national park are appealing to the public for information and witnesses after more than 30 sites in the park were vandalized with spray paint last month.
Park officials are asking anyone who was on the trail to the top of Yosemite Falls on 20 May and who saw people carrying cans of spray paint and tagging the area to contact the National Park Service.
Vandals used white and blue spray paint to draw on boulders and other sites along the Yosemite Falls trail, park officials said in a Facebook post on Sunday.
At approximately 8.15pm on 20 May, park rangers received reports of vandalism along the trail. When they assessed the damage the next day, they found more than two dozen places where graffiti had been spray-painted, officials said.
Photos posted on social media show rocks tagged with the word “Fresno” and other illegible writings.
The smallest graffiti measured 1ft by 1ft(30cm by 30cm), but most were 3ft by 3ft and a few were larger than 8ft by 8ft, officials said.
A spokesperson for the national park denounced the vandalism as “egregious”, SFGate reported. “For someone to take a beautiful area and do this, it’s beyond upsetting,” Scott Gediman said in a statement to the newspaper.
