LUENGO 2003 "Distribution and effectiveness of nivation in mediterranean mountains: Penalara (Spain)".
The ice patches are confined to northwest-, north-, or northeast-facing slopes, often within cirques or nivation hollows (Washburn, 1979), and they range from less than 100 m to almost a kilometer in length and from about 10 m to more than 80 m in height.
Reger and Pewe (1976) suggest formation of the surfaces is largely due to scarp retreat as the result of nivation.
