- •
The age distribution of stalagmites from Sulawesi follows an exponential relationship.
- •
This relationship appears globally and is likely a general cave phenomenon.
- •
Natural attrition of stalagmites is generally constant over long (> 100 kyr) time scales.
- •
Deviations from this ideal relationship indicate changes in palaeoclimate.
- •
High frequency stalagmite growth in Sulawesi corresponds to wet periods in Borneo.
