Image number: 2007
Feature : rills
Grouping : caves
Discipline : geomorphology
Year : 1995
Locality : Tree shelter valley, Sodmein
Country : Egypt
Region - tribe : Quseir
Physiographic region : Desert-Red Sea Mountains
Notice : Cavities, galleries, rock shelters and caves are developed in the Thebes Limestone. They are probably karstic in origin bu evolve at present by physical weathering. Their relation with existing fissures is clear. In this case the rills start from a vertical shaft which clearly provided the water. The size of the debris excludes that they are coming from the inside of the shaft. They are detached from the ceilings.
