This happened in Joshua Tree, not Yosemite, but is a reminder to park-lovers that not everyone loves parks or nature; or if they do, they love them for the wrong reasons. Unfortunately, we share the planet with some people who we wish would have been born on Uranus.
A portion of the park has been closed, not because of storm damage or a rockslide, but because of the actions of some thoughtless and contemptible individuals who painted graffiti on natural and historic features. This is not the first time a national or state park has been defiled by two-footers, but it never ceases to make us angry.
If you see human-caused damage in a national park, report it to rangers or a visitor center ASAP. If you witness an incident, don’t make contact, but observe as much as you safely can to pass on to the rangers. Standard suspect descriptions include number of people, and as much of the following as you can get on any of them: sex, race, approximate age, height, build, hair and eye color, clothing when last seen, distinguishing features (scars, tattoos, prosthetics, accent, language spoken). Standard vehicle descriptions include color, year, make, body type, distinguishing marks or features, and license number or at least state of origin or license plate color. If you aren’t good with vehicles, “blue or gray late 90s midsize American sedan with Nevada plates” or “light colored older small pickup with patches of red primer on the fenders, white license plate with green lettering” is better than nothing. If the suspects left, note their direction of travel.
No one goes to a national park without a camera, so if it’s safe to do so, take a photo or two. When you report it, be as exact as you can about the place and time of occurrence. The better report you make, the better the chance of finding and prosecuting these creatures.
