scree

Etymology 1

Probably a back-formation from screes, from Old Norse skriða (“landslide, landslip”); compare skríða (“to glide”) (from Proto-Germanic *skrīþaną (“to crawl; to glide; to walk”), from Proto-Indo-European *(s)kreyt-, *(s)ker- (“to bend, turn”)). The word is cognate with Icelandic skriða (“avalanche; landslide, landslip; steep mountain- or hillside made up of gravel and loose rocks”).

   Also, special to Crete, and probably derived from some aspect of its climactic history, is cementation. Many screes are converted, in whole or in part, into concrete-like breccias. Carapaces of cemented scree encrust steep slopes. Cliffs of conglomerate or marl are covered with a layer of re-deposited limestone and look like hard rock. However, the loose contents are apt to trickle out through a breach in the crust, resulting in the jagged and hollow cliffs which are a picturesque feature of Crete 2008, I[oannis] N[ikolaou] Vogiatzakis, O.
