Scree is an accumulation of unconsolidated angular rocks. Seeon Wikipedia.
More specifically scree is formed by rockfall from adjacent rockfaces and often accumulates in the form of sloped cones called talus. Scree consists of rock fragments with sharp edges that can vary in size from millimeters to meters.
How to map
To map an area of scree you can just draw a line closing on itself, marking the area of scree and tag it natural=scree. To map large scree covered areas you can use Relation:multipolygon with the same tag.
