A picturesque canyon in Joshua Tree National Park that was scarred by graffiti will remain closed due to an extensive clean-up operation, officials said Tuesday.
Rattlesnake Canyon was defaced by vandals who used social media to boast about their exploits, park officials said.
The popular hiking area was shut down earlier this month and was scheduled to reopen today. But park officials said that the extensive damage will require that the area be closed for at least 30 more days while crews work to remove the graffiti.
Park rangers began noticing the scrawls in January. The vandalism of rocks and archaeological sites outraged visitors and park officials.
