A part of the glacier, and especially of the glacier surface, distinguished from other parts by the prominence or predominance of a particular mass-balance process. The temperate glacier of Figure 15 and the cold glacier of Figure 16 are end members of a continuum. Many glaciers have attributes, including patterns of zonation, that are intermediate between these end members. The conventional system of zones in the English-language literature diverges in part from that in Russian-language work (Shumskiy 1955). For the latter, which is based on the relative magnitudes of accumulation, melting and cold content.
