In November 2010, the Bradshaw Foundation released the news of discoveries by two Arizona rock art specialists, Ekkehart Malotki of Flagstaff and Henry Wallace from Tucson, of mammoth depictions in North America. The petroglyphs were incised high on a sheer cliff of Navajo Sandstone bordering the floodplain of the San Juan River in southeastern Utah.

The petroglyphs are now presented by Ekkehart Malotki and Henry D. Wallace in a paper in Rock Art Research, vol. 28, No. 2, pp. 143-152, November 2011, entitled 'COLUMBIAN MAMMOTH PETROGLYPHS FROM THE SAN JUAN RIVER NEAR BLUFF, UTAH, UNITED STATES'

Abstract. Authentic petroglyph portrayals of Columbian mammoths and a bison at the Upper Sand Island rock art site along the San Juan River in south-eastern Utah in the United States are described and illustrated. Evidence is presented supporting their authenticity, including rock varnish and wear observations and comparisons to nearby Puebloan and Historic period petroglyphs, depiction of anatomical details not commonly known to the public, depiction of relatively small tusks (which differs from typical public perceptions), and the presence of accompanying motifs produced in a similar previously unknown style. The most likely dating of the motifs is between 13 000 and 11 000 years BP.
