Collapsed Ice-Floored Lakebed Technical Terms
Collapsed Ice-Floored Lakebed: A lakebed formed in a lake on glacial ice and subsequently "let down" or collapsed by the melting of underlying ice, resulting in contortion or folding of the lacustrine sediment and sedimentary structures. These modified or distorted lacustrine sediments cap present-day topographic highs and generally lie at elevations higher than the surrounding disintegration moraine. Compare - collapsed lake plain, collapsed ice-walled lakebed. SW & CF
