|A Leviathan in the Desert (Toños)
Toños is a Great Mural site containing an incredible life size painting of an orca (killer whale). This is the largest pictograph in the world! There is much general information in the talk about orcas and the art and rock art inspired by them done by native peoples in North America. I gave this talk at ARARA 2019 in Flagstaff and Rock Art 2019 in San Diego. It was published in American Indian Rock Art 46:97-106 (PDF).
Codornices: Great Mural Painted Sites in Baja
California north of the known boundaries of Great
Rancho Codornices has Great Mural pictographs of striking beauty in addition to Northern Abstract sites. I have given this talk at
of the Great Mural Artists
An important use of rock art to document the migration of peoples. A paper based on the presentations has appeared in Rock Art Papers v18, edited by Ken Hedges and published in 2016 by the San Diego Rock Art Association. Here is a PDF (9mb). I have given a variant of this presentation at several conferences in 2014 and 2015: Balances (in La Paz for the first time), Rock Art (San Diego), MORAW (Zzyzx), SCA (Redding), SAA (San Francisco), and IFRAO (Cáceres, Spain).
I describe two sites
from the Sierra de San Borja and show a connection between
the art there and the Sierra de Guadalupe. This may
indicate the place of origin of the San Borja
painters. Presented at the ARARA 2014 conference in
Rock Springs, WY.

patterns that can be recognized. Presented at the
