In 1901, Hartz and Milthers found a roughly 30 cm layer of gytja at Allerød in North Zealand, Denmark. Sandwiched between glacial clay deposits, it contained birch and juniper remains, indicating milder conditions between two colder stages. The discovery first demonstrated the Allerød interstadial, the late-glacial warm interval between the Older and Younger Dryas.

Key facts
- In 1901, Hartz and Milthers identified the Allerød fluctuation from a roughly 30 cm-thick gytja layer at Allerød in North Zealand, Denmark.
- Gytja is dark, organic-rich mud deposited in freshwater marshes and lakes.
- The layer lay between glacial clay deposits and contained birch and juniper remains, indicating climatic amelioration between colder stages.
- The discovery first demonstrated the Allerød interstadial, a late-glacial warm interval between the Older and Younger Dryas.
