When these two formations are overlain by glacial outwash
, average household radon levels are even greater.
Glacial lakes were created when ice blocks from receding glaciers became embedded in the glacial outwash
and melted forming kettle holes that filled with water (Petersen et al.
Our farmhouse was on a gravel ridge, likely a glacial outwash
terrace, and our front yard was in the flood plain of the Great Miami River.
Laterally extensive cemented beds have been recorded in five outcrops hosted in glacial outwash
and beach sand and gravel deposits that accumulated during the Late Weichselian deglaciation about 15.7-12.5 ka BP (Kalm 2006; Kalm et al.
The rolling hills of steep moraines and glacial outwash
plains Forests, prairies, and wetlands emerged from the land so fair.
Professor Joseph Prospero, from the University of Miami has said: "Our work has shown that most of the dust events are associated with dust emitted from glacial outwash
deposits, which may be carried into the northern latitudes by synoptic weather events."
"Our recent work in Iceland has shown that most of the dust events there are associated with dust emitted from glacial outwash
deposits, which may be carried into the northern latitudes and into Europe by synoptic weather events," said Prospero.
Coarser material, being larger and heavier, was deposited near the glacier and in streams and rivers to form glacial outwash
. Outwash soils tend to be sandy.
Although located in the Tipton Till Plain province, the White River floodplain was modified by late stage glacial outwash
. One of the boring logs for the site is presented in Fig.
Late Pleistocene fluvial deposits of the Lower Mississippi Valley (LMV) in Louisiana are thought to represent Mississippi River glacial outwash
. Recent studies, however, show that red sediments of probable Arkansas River origin occur beneath several LMV terraces.
