SLADE, Ky. (AP) - Federal forestry officials say there is a growing graffiti problem at Kentucky's popular outdoor destination, Red River Gorge.

The geological area is a favorite with hikers and rock climbers, but officials say vandals are becoming all too common.

The area in eastern Kentucky is part of the Daniel Boone National Forest. Red River Gorge manager Tim Eling says carving and spray painting on exposed rock features is increasing. Eling says they are seeing more brightly-colored spray paint on rock surfaces.

Eling says it is costly to remove the paint from the area's sandstone features.

Visitors are encouraged to report vandalism to the nearest Forest Service office. A release from forestry officials says those caught vandalizing will be fined and prosecuted in federal court.
