The loss of the ice caves is not just about losing a beautiful underground landscape, but also about losing an important scientific resource. Like tree rings that can be analysed for climate information, the layers within the ice can also provide climate information. The nature of their formation means the records reveal details of past winter seasons. Organic material trapped within the ice can be radiocarbon dated to find out when the ice was deposited. #EndOfTheIceCaves #IceCaves @NatGeo @Natgeointhefield
