Estonia is a comparatively flat country inexplicably peppered with large granite boulders...that is, the location of these natural curiousities was inexplicable until the 19th century theory of continental glaciation explained their derivation. But in the centuries before science came to value glacial erratics as geological specimens, early Estonians treasured the objects as powerful but benign manifestations, symbols of stone that spoke to the mysteries of the natural world. Early Estonians composed elaborate folklore to explain and honor the boulders, but increasingly in the 19th and 20th centuries, both the boulders and the living folklore tied to them became threatened by industrial encroachment. This essay will analyze the intricate nexus between national imaginings and efforts to preserve Estonia's glacial erratic boulders. It will illustrate varying motivations for boulder preservation and clarify the means by which patriotically inclined Estonian nationalists re-interpreted one of their nation's most salient natural features to, in many ways, represent the nation itself.
