UNM helping clean up Joshua Tree graffiti

ALBUQUERQUE, N.M. — Ian James at the Desert Sun (Palm Springs) had a neat story this morning about work a University of New Mexico researcher is doing to help clean up graffiti on the historic Barker Dam at Joshua Tree National Park in the desert of southeastern California:

Last week, park employees tried out various approaches for removing or masking the graffiti during a visit by researchers Angelyn Bass of the University of New Mexico and Douglas Porter of the University of Vermont. The two have experience in rock art conservation and the conservation of historic structures, as well as with graffiti cleanup efforts.
