The Oldest Dryas was a climatic period, which occurred during the coldest stadial after the Weichselian glaciation in north Europe. In the Alps, the Oldest Dryas corresponds to the Gschnitz stadial of the Würm glaciation. The three “Dryas” periods (younger, older, oldest) are named for a marker species, Dryas octopetala, detected in core samples of glacial ice and peat bogs. The Oldest Dryas corresponds to pollen zone Ia.

Famous quotes containing the word oldest:
“The United States is just now the oldest country in the world, there always is an oldest country and she is it, it is she who is the mother of the twentieth century civilization. She began to feel herself as it just after the Civil War. And so it is a country the right age to have been born in and the wrong age to live in.”
—Gertrude Stein (1874–1946)
