In April 2019, I went on a field trip to see petroglyphs & pictographs in Harney County, in eastern Oregon. This is one of the many trips offered as a part of the Harney County Migratory Bird Festival. Our guides that day were Bureau of Land Management archaeologists, Scott Thomas and Carolyn Temple.
One of the first things we learned was the difference between petroglyphs and pictographs.
Pictographs
Pictographs, like the images shown below, are painted onto rocks. These works are generally drawn with red, black, white, or yellow paint.
Pictographs frequently include depictions of animals. For example, the drawing at the top of the picture below appears to be a lizard.
