Ground-penetrating radar (GPR) was used to analyse the circular Vaidasoo bog in northern Estonia. This was done to better understand its structure and origin, and to test the suggestion that Vaidasoo represents a meteorite impact structure. The combination of GPR with LIDAR data suggests that Vaidasoo bog is developed in a NW–SE oriented glacial tunnel valley where post-glacial hydrology is affected by glaciofluvial deposits. As no clear impact-modified bedrock features were identified and the circular bog does not mirror the topography of the bedrock, we conclude that the Vaidasoo structure does not represent a meteorite impact structure.
