Definition: Part of an ice stream raised slightly higher, and flowing slightly more slowly, than surrounding ice. The attributes that define the ice raft suggest that basal sliding is relatively slow at its bed, and therefore that it might represent a persistent 'sticky spot'.  IHPGlacierMassBalance 

A discrete block of slow-moving land ice that has been incorporated en masse into either an ice stream or an ice shelf.  AMSglossary
