692 viewsOne of the most studied and interesting ice streams in Antarctica, Ice Stream B shows a number of features that indicate past changes and ongoing evolution. In this subscene the upstream ends of several ice stream shear margins are highlighted. Characteristic crevasse patterns, nicknamed "chromosomes," mark the ends of several of these margin traces.
