Description :
This paper concerns the latter aspects by providing morphological details and Schmidt hammer (rock hardness/weathering) data from a large rock slope failure at the mouth of Urdadalen, in the Jotunheimen. It is believed that this represents the first example of such a feature to be reported from this area. The localised geomorphological impact of this failure event has been to dam the valley and create a small lake, to cause valley widening, to produce a north-facing hillside embayment above sea level with the potential to collect and retain snow that might, in future, lead to niche glacier development and cirque initiation, and to provide a large volume of rock debris for entrainment and onward transport in future glacial cycles.
