In August, 2010, rangers discovered that vandalism had occurred at an archeological site in the park where historic signatures had been inscribed by famous western personalities Butch Cassidy, Matt Warner, and Silvertip. The recently inscribed names of at least eight individuals, along with the year 2010, were etched into the walls of the alcove near the historic inscriptions. By investigating Facebook postings, rangers were able to identify the responsible individuals as a result of information that they had posted about their recent family reunion in the park. Once identified, members of the group took full responsibility. They paid a total of $6,045 for site restoration under the authority provided by the Park System Resource Protection Act (16USC 19jj). Professional restoration of the site will commence this year. Ranger Brenda Zirwas was the case ranger.
