This month marks the 69th anniversary of world’s first atomic plume rising into New Mexico’s sky. The day the nuclear bomb went off, there were 19,000 people living near the Trinity test blast site, including Native Americans of several tribes and pueblos. Residents weren’t given any warning of the detonation, and the health effects lingered through the decades—but those facts aren’t yet part of public conversation or historic memory.
