When rivers move borders: PhD student writes on boundaries and belonging in the Colorado River borderlands
In 1907, Cocopah Indians who had been living in Mexico suddenly found themselves farming land in the United States. The Colorado River that marked the border between the U.S. and Mexico had moved around them. That stretch of the Colorado River shifted unpredictably across its floodplain before the Hoover Dam was completed in 1936. The conflicts and alliances that arose from this ever-changing landscape are the focus of Daniel Grant’s dissertation on belonging and exclusion in the U.S.-Mexico borderlands from the late-19th through mid-20th centuries.
