Collapsed Ice-Walled Lakebed Technical Terms
Collapsed Ice-Walled Lakebed: A lakebed that formed in a lake bounded by stagnant ice, but floored by solid ground, usually till. Collapse features are limited to the lakebed margins. Presently, these materials and sedimentary structures generally occur as roughly circular-shaped hills of till capped by lacustrine sediments, generally at elevations higher than surrounding disintegration moraine. Compare - collapsed ice-floored lakebed, collapsed lake plain. SW & CF
