Abstract

Ring forms are a type of landform consisting of a series of ridges and troughs with a circular, sinuous, and anastomosing morphology. This striking landform was initially identified in the Canadian High Arctic on the south coast of Devon Island, Nunavut, Canada. Here, we report on the identification of ring forms near Mokka Fiord on Axel Heiberg Island, Nunavut, Canada. Utilizing field observations, ultra-high-resolution light detection and ranging (lidar), and ground-penetrating radar (GPR), we characterize and compare the morphometry and sedimentology of ring forms at Mokka Fiord with other similar periglacial, paraglacial, and glacial landforms. The Mokka Fiord ring forms range in diameter from 6 to 37 m and reach up to 1.5 m in height and are composed of clast-rich glaciofluvial sediment and till.
