Il ghiacciaio di Pré de Bar (pron. fr. AFI: [pre də baʁ]) si trova nel massiccio del Monte Bianco nel versante valdostano.

Caratteristiche

La parte centrale del ghiacciaio di Pré de Bar.

La sua estensione misura circa 340 ettari. Si trova nella val Ferret (Courmayeur). È contornato da importanti vette: aiguille de Triolet (3.874 m), punta di Pré de Bar (3.659 m), mont Dolent (3.819 m) e mont Grapillon (3.576 m).

Le sue caratteristiche principali sono: lunghezza 3,9 km circa, larghezza massima 1,5 km circa, esposizione sud-est, quota massima 3750 metri circa, quota minima 2150 metri.

Formato fino a inizio anni ottanta del Novecento da un bacino di accumulo e da una spettacolare lingua di ablazione, si è ridotto negli anni a seguire; la lunga lingua, un tempo palestra per imparare le tecniche di progressione su ghiacciaio, è scomparsa completamente tra il 2010 ed il 2015.[1]

Accesso

Il rifugio Elena, raggiungibile con una facile camminata da Arnouva, rappresenta il luogo ideale per osservare la conca formata dalla lingua di ablazione oggi scomparsa, conca a monte della quale è visibile ciò che resta del ghiacciaio.

S-layer

An S-layer (surface layer) is a part of the cell envelope found in almost all archaea, as well as in many types of bacteria.[1][2] The S-layers of both archaea and bacteria consists of a monomolecular layer composed of only one (or, in a few cases, two) identical proteins or glycoproteins.[3] This structure is built via self-assembly and encloses the whole cell surface. Thus, the S-layer protein can represent up to 15% of the whole protein content of a cell.[4]...
