Abstract
The basal organic deposit in many Minnesota lakes includes wood fragments and other coarse plant material of terrestrial origin, along with diatoms characteristic of soils, moss, and other terrestrial habitats. The material probably represents the floor of a superglacial forest; it is overlain by similar material deposited in shallow pools that formed when buried Wisconsin dead ice melted beneath a cover of till or outwash.
