Abstract

A tongue-like, boulder-dominated deposit in Tverrbytnede, upper Visdalen, Jotunheimen, is interpreted as the product of a rock avalanche (landslide). Lichenometric dating of the deposit indicates an approximate emplacement age of AD 1900. The analysis highlights the interaction of rock-slope failures and glaciers during deglacierization in a neoparaglacial setting, with reduced slope stability due to debuttressing and permafrost degradation, and enhanced landslide mobility due to flow over a glacier and topographic channelling. Implications for the differentiation of relict landslides, moraines and rock glaciers are discussed and interrelationships between these landforms are considered in terms of an ice-debris process continuum
