Lake Bonneville was not a proglacial lake although it formed between about 30,000 and 13,000 years ago, when glaciers at many places on Earth were expanded relative to today during the last major glaciation. [5]
Lake levels in the Erie Basin of the Laurentian Great Lakes. Journal of Paleolimnology 47:493-511. Early Lake Erie was a prehistoric proglacial lake that existed at the end of the last ice age approximately 13,000 years ago.
Decades before this Great Lakes site became a national park in 2000, severe pollution ravaged the Cuyahoga River – so much so that the river caught on fire a dozen times. In 1969, the river ...
