Glacier = a slowly moving river of ice formed by the accumulation and compaction of snow
Wikipedia: Glacier = Persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries.
