The Younger Dryas lasted ~1,200 years (12,900–11,700 years ago), causing major ecosystem disruption at the Pleistocene's end. This cooling period profoundly reshaped the continent.
Younger Dryas climate disruption coincided with horse extinction timeline
Key facts
- The Younger Dryas lasted approximately 1,200 years, from about 12,900 to 11,700 years ago (roughly 10,950 to 9,750 BC)
- Represented a major climatic disruption at the end of the ice age
- Transition from the late glacial world into the early Holocene profoundly altered vegetation, water availability, animal distributions, and human subsistence strategies
- Conventional extinction boundary for North American horses is placed between approximately 13,000 and 10,000 years ago (roughly 11,000 to 8,000 BC)
