Episode 51 -- The Bone Gardens of Armero

Welcome, agents. Tonight's operation takes us to Colombia, specifically to the ghost town of Armero in the Tolima Department. For those unfamiliar, Armero was buried by a lahar—a volcanic mudflow—when Nevado del Ruiz erupted on November 13th, 1985. Over twenty-three thousand people died in a single night, their bodies entombed beneath thirteen feet of volcanic debris. The Colombian government declared the site a holy campo santo—a sacred cemetery—and banned excavation. But something has changed. Three weeks ago, satellite imaging detected unusual subsidence patterns across the former town site. Then, a team of Colombian geologists went to investigate and vanished. Delta Green has intercepted communications suggesting their discovery went far beyond geological anomalies. Your cover: a joint DOI archaeological survey assessing potential UNESCO heritage site violations. Your actual mission: determine what happened to the geological team and neutralize any unnatural threat.
