Graffiti in Widow’s Ledge archaeology site. Widow’s Ledge archeological site protects multiple dry-stacked masonry structures. Graffiti and vandalism in sites like this detract from the site’s integrity and causes damage. Unfortunately, even if graffiti can be removed, removal will often leave behind significant scars, and is not always possible or advisable/NPS file

Glen Canyon National Recreation Area in southern Utah and northern Arizona covers 1.25 million acres, but fewer than 125,000 acres have been surveyed for archaeological sites using modern standards, according to the National Park Service.

In the coming 12 months the NRA staff will work with the Museum of Northern Arizona to complete archaeological surveys along several road corridors throughout the park where a previous survey has not yet been done.

Specifically targeted will be areas where off-road vehicle traffic has been increasing, and where damage to archaeology sites from off-road vehicles is possible, according to the park staff.

Another project will work to mitigate vandalism at a number of archaeological sites that have been heavily damaged by graffiti.

"We will also be completing several historic preservation projects on historic wood and masonry structures," the staff noted in a newsletter.
