Cliff Trafzer’s new book uses oral tradition to offer an alternate interpretation of ‘The Last Western Manhunt’

More than a century ago, a Romeo and Juliet-esque tragedy unfolded in the desert southwest. The antagonist, Willie Boy, shot and killed the shaman, William Mike, and eloped with William Mike’s daughter, Carlota, who met her demise at the hands of the pursuing posse. 

The story has been framed and reframed for generations from the settler perspective, including the Harry Lawton book “Willie Boy” and a 1969 Hollywood movie starring Robert Redford and Robert Blake. The resulting narrative has endured in large part because cultural law has prevented the Chemehuevi community from speaking of the dead. 

Clifford E. Trafzer, distinguished professor of history and Costo Chair in American Indian Affairs at UC Riverside, explores this fateful saga from the perspective of the Native community in his book, “Willie Boy & The Last Western Manhunt.”

Boy meets girl

Willie Boy was born into a Nuwuvi family in the Chemehuevi Valley in 1882. He entered the world at a contentious time as more white settlers pressed into the area in search of gold, land, and opportunities. Willie Boy learned the values of his culture as he walked the path of his ancestors. He also adapted to the white culture, learning English and working alongside white ranchers. As he grew, the cultural tug-of-war led to the misstep that set tragedy in motion.

A new study explores a possible proxy for seasonal freshwater input that could elucidate changes in alpine snowpack as the planet warms.

As the planet warms, the winter season is growing shorter and warmer. The consequences of these changes are particularly problematic in alpine regions. These areas are being robbed of the time and temperature to accumulate an adequate snowpack to supply the valleys below with fresh water throughout the spring and early summer. Understanding how the snowpack has changed is critical, but snow is ephemeral, and the research community has lacked a proxy to record and reconstruct seasonal river flow.

Now a Japanese team of researchers is using the geochemical signature obtained from the shells of freshwater bivalves to find this critical piece of information. The results of their study, published in Palaeogeography, Palaeoclimatology, Palaeoecology, produced an almost 7-decade seasonal record of river flow in northern Japan.

“The proxy and/or geological records that could reconstruct the river environmental condition in the past are very limited,” said Tsuyoshi Watanabe, a lecturer at Hokkaido University and first author on the study. “I was surprised that [the shells of] these long-living [mussels] could capture very detailed information about river environments [at a] daily scale.”

Enter Margaritifera

For more than 4 decades, geochemical records obtained from the shells of bivalves, microplankton, and corals have proven to be effective proxies to reconstruct past environmental conditions, including temperature, salinity, and dissolved oxygen. In this study, Watanabe and his team focused on the freshwater mussel species Margaritifera, which has a pronounced life span of up to 200 years. Previous studies have found that the annual growth patterns of this species reflect temperature and precipitation during the summer months. Watanabe and his team set out to determine how the timing and chemistry of growth bands on the shell material correlated to the vast amount of environmental data for the region around the Shiribetsu River, where colonies of the mussel are common.
