# Diatoms constrain forensic burial timelines: case study with DB Cooper money

Thomas G. Kaye, Mark Meltzer, 2020. _Scientific Reports 10, 13036_.

Identifies diatoms adhering to the Tena Bar bills and compares them with the seasonal bloom cycle of the Columbia River, concluding that the bills were immersed in spring or summer, months after the November 1971 jump, and then buried.
