Short summary
This study investigates enigmatic ring forms found on Axel Heiberg Island (Umingmat Nunaat) in Nunavut, Canada. These ring forms comprised a series of ridges and troughs creating individual rings or brain-like patterns. We aim to identify how they form and assess the past climate conditions necessary for their formation. We use surface and subsurface observations and comparisons to other periglacial and glacial ring forms to infer a formation mechanism and propose a glacial origin.
