dead-ice

This insulation did not hinder parts of the ice to melt, creating ponds between the till-covered dead-ice.

Dead-ice occurs when a glacier or ice sheet ceases to move and melts in situ.

Dead-ice was preserved in the hollow thus formed; when that melted the lake was formed.

When the ice sheet retreated, dead-ice (Toteis) remained deep in these channels; it was their thawing that then enabled the rivers to flow down their old valleys.

Landscape forming Veiki moraines in northern Sweden and Canada have been ascribed as the result of ablation of extensive bodies of till-covered dead-ice.

Veiki moraines are believed to have been formed by supraglacial till that during the late Saale glaciation or the early Eemian interglacial partially protecting dead-ice from melting.

Some of these theories proposed that Rogen moraines had an origin as a series of end moraines, that they formed in association with calving ice termini in glacial lakes, or that Rogen moraines formed in dead-ice, where supraglacial material fell down into crevasses in the ice.
