40,000 Years of Life & Death: Excavations in Spain's El Miron Cave

The Oregon Archaeological Society is pleased to sponsor the March 5, 2013 lecture titled: "40,000 Years of Life and Death in a Spanish Cave: Excavations in El Miron, Cantabria."  

The featured speaker is the distinguished Dr. Lawrence Guy Straus, the Leslie Spier Distinguished Professor of Anthropology at the University of New Mexico College of Arts and Sciences.

El Miron Cave, located in the Cantabrian Cordillera in Spain has been excavated by Professor Straus and a Spanish colleague since 1996.  Scientifically discovered in 1903, but ignored by archaeologists despite being surrounded by cave art sites, El Miron is a large cave with a strategic location.  First visited by Straus in 1973, it has yielded results beyond his wildest expectations.  

The cultural sequence begins in the late Middle Paleolithic and continues through evidence of Medieval visits, with radiocarbon dates ranging from 41,000 BP to AD 1400. As the surrounding environment changed, the evidence of human use of the cave also changed.

 The site has been the subject of numerous multidisciplinary studies of the climate, landscapes, human technology, subsistence, and artistic activity that have resulted in dozens of publications in Europe and the U.S.  Major discoveries have included dated portable art objects, rock engravings, an associated human burial, evidence of human occupation and livestock stabling, and ceramic and metal technology.

Straus has conducted excavations in Spain, France, Portugal, and Belgium, principally at Upper Paleolithic (but also Middle Paleolithic, Mesolithic and Neolithic) sites.  He is particularly interested in human adaptations to the diverse and changing environments of the Last Glacial in Western Europe.  

He has authored numerous publications and has been the Editor-in-Chief of the Journal of Anthropological Research since 1995. He has been given lifetime achievement awards by the Stone Age Institute at Indiana University and the Sociedad Prehistorica de Cantabria, and has held offices in the international unions for Quaternary Research (INQUA) and Pre- and Proto-historic Sciences (UISPP).

The presentation is at Oregon Museum of Science and Industry (OMSI) is free and open to the public. A general business meeting begins at 7 PM, followed by the lecture.

Petroglyph Canyon Historic Photos

For thousands of years native people carved and painted spiritually important images on the basalt cliff faces of what came to be known as Petroglyph Canyon. The canyon is located in south central Washington state near Columbia Hills State Park (see image below).

Petroglyph Canyon was reported to have one of the largest concentrations of Indian rock art in North America before it was largely submerged in the pool behind The Dalles Dam (photo below) in 1957. Today much of the rock art, and the canyon itself, lie hidden beneath the waters of Horsethief Lake and the Columbia River at Columbia Hills State Park near Dallesport, WA.

We recently came across a website ( that displays (and sells) historic photographs.  John Klatt, who owns the Old Oregon website, has graciously allowed CultureWatch NW to reproduce some very old photos of Columbia Gorge rock art. (All historic photos in this post are © Old Oregon Photos).

As the giant hydroelectric generation dams were built on the Columbia River beginning in the 1930's many Native American cultural areas, including rock art sites, were flooded by the large lakes that formed behind them. Photographers, professional and amateur, scrambled to record the ancient images before they disappeared. 

By the way, if you have old photos of rock art from the Columbia Gorge and are willing to share them we would love to hear from you! Just send an email to

A number of petroglyphs and pictographs were actually "salvaged" by being physically removed from areas about to be submerged. Some of these rescued boulders, including a number of those shown in the old Benjamin Markham photos in this article, can be seen today along the Temani Peshwa Trail (photo below) at Columbia Hills State Park and at the Ginkgo Petrified Forest Recreation Area near Vantage, WA.

So let's take a look at the old photos! When available we've included both a historic picture (black and white) and a modern photo (color) so you can see how the rock art has changed in the last 75-100 years.

The photo on the left below was taken by Benjamin Markham in the 1920's. It shows the panel of petroglyphs in situ, still part of the cliff wall at Petroglyph Canyon. The same panel is visible at center left in the Willis Vail photo above. On the right below is the salvaged panel, now located on the Temani Peshwa Trail.


You will notice that the contrast between the petroglyphs and the background rock is much greater in the old photos. Historically it was a common practice to color or outline rock art with white chalk to make the images show up clearly in photos. This practice is now regarded as vandalism because it may take decades for the chalk to disappear.

The photo on the left (attributed to Markham but unsigned) was taken near Wishram, WA. A modern photo shows the beautiful color of the images which are a combination of petroglyphs and pictographs (painted on the rock surface).

The two photos below were also taken by Markham 
in the 1920's. Unfortunately we don't have any modern 
photos to compare them with. The image on the left was taken 
in Petroglyph Canyon and is now assumed to be 
submerged. The other was taken at a rock art site in 
Sherman County, Oregon.

Check out the historic photos at and when the weather warms up (after April 1) head out to Columbia Hills State Park where you can take a self-guided tour of the Tamani Peshwa Trail (whenever the park is open) and also a free guided tour of the other extensive rock art sites at the park (reservation required for the free tour, there is a small fee to enter the park).
