Helmersen Rock Field
In 1871 and 1879, Russian geologist Gregor Helmersen was the first to describe and characterize the Heilu rocks. His name is also connected to rocks elsewhere in Estonia. He described the Helmersen Rock Field as the best group of boulders originating from Finland that he had seen in the Baltic countries. There are over 80 rocks on the 0.5-hectare-size plot, which been carried here by the glacial ice.
