Mont Saint Helens : Diferéncia entre lei versions

Pendent l'ivèrn de 1980–1981, un [[glacièr]] nòu apareguèt. Uèi oficialament nomenat [[Crater Glacier]], èra ancianament conegut jol nom de Tulutson Glacier. Ombratjat per las parets del cratèr e alimentat per las importantas casudas de nèu e avalancas, creissèt rapidament (4.3 m per an). En 2004, cobrissiá aperaquí 93 km2, e èra devesit per lo dòma central en dos lòbes. Generalament a la fin de l'estiu, lo glacièr es fosc amor de las casudas de ròcas del cratèr e de cendres de las erupcions.

The ice is all post–1980, making the glacier very young geologically. However, the volume of the new glacier is about the same as all the pre–1980 glaciers combined.<ref name="Brugman81">{{cite web | last = Brugman | first = Melinda M. | coauthors = [[Austin Post]] | title = USGS Circular 850-D: Effects of Volcanism on the Glaciers of Mount St. Helens | url= http://pubs.er.usgs.gov/publication/cir850D | year = 1981 | accessdate = 2007-03-07 }}</ref><ref name="Wiggins02" >{{cite journal | last = Wiggins | first = Tracy B. | coauthors = Hansen, Jon D.; Clark, Douglas H. | title = Growth and flow of a new glacier in Mt.
