In 1969, after weeks of relentless rain on Santa Fe Island, erosion carved deep channels into the soil and exposed a remarkable find. While out observing hawks, Tjitte de Vries — the first resident scientist of the Charles Darwin Research Station — noticed a small, perfectly preserved tortoise skull among the washed-out gravel. He carefully brought it back to the station, where he and then-director Roger Perry realized it might belong to the long-extinct giant tortoise of Santa Fe.
