| Abstract | In this paper we use the example of Ellef Ringnes Island, Nunavut, to examine active geomorphic processes in a high latitude semiarid region. The spectacular landscape of Ellef Ringnes Island is
principally the result of fluvial erosion controlled by geological structure.
The nival regime concentrates flow in a brief late-spring period which provides strong erosive capabilities for rivers in spite of low annual precipitation. Other
processes related to the cold environment produce a variety of minor landforms such as patterned ground, mud
flows associated with ground ice, and solifluction lobes. |
