It includes the Sloan Petroglyph Site which was listed on the National Register of Historic Places on December 19, 1978.

[1] Sloan Canyon contains a great many petroglyphs and has been called the Sistine Chapel of Native American rock art due to their size and significance.

[3] Archaeologists believe the more than 300 rock art panels with 1,700 individual design elements were created by native cultures from the Archaic to historic eras.

The BLM currently maintains a policy of not publicizing the exact location of the petroglyphs due to recent problems with vandalism.

Sloan Canyon NCA is (as of November 2006) closed to camping, shooting and offroad vehicle access, due to dumping and vandalism.
