Short summary
We studied bedrock fracturing at Åland Islands from bedrock outcrops, digital elevation models and geophysics using multiple scales of observation. Using the results we can compare properties of the fractures of different sizes to find similarities and differences; e.g. we found that glacial erosion has a probable effect on the study of larger bedrock structures. Furthermore, we collected data from 100 to 500 m long fractures, which have previously proved to be difficult to sample.
