High Quality Content by WIKIPEDIA articles! Glacial Lake Maumee was a proglacial lake that was an ancestor of present-day Lake Erie. It formed about 14,000 years ago. As the Erie Lobe of the Wisconsin Glacier retreated at the end of the last ice age, it left meltwater in a previously-existing depressional area that was the valley of an eastward-flowing river known as the Erigan River that probably emptied into the Atlantic Ocean following the route of today's Saint Lawrence River. Some geologists think that the Erigan could have been a downstream segment of the preglacial Teays River system.…mehr

High Quality Content by WIKIPEDIA articles! Glacial Lake Maumee was a proglacial lake that was an ancestor of present-day Lake Erie. It formed about 14,000 years ago. As the Erie Lobe of the Wisconsin Glacier retreated at the end of the last ice age, it left meltwater in a previously-existing depressional area that was the valley of an eastward-flowing river known as the Erigan River that probably emptied into the Atlantic Ocean following the route of today's Saint Lawrence River. Some geologists think that the Erigan could have been a downstream segment of the preglacial Teays River system. The glaciers destroyed or disturbed most of the preglacial drainage patterns and enlarged and deepened the Erigan basin. As the Erie Lobe retreated to the northeast, it left large debris deposits called moraines running at right angles to its line of retreat. One of these, called the Fort Wayne Moraine, was left at the site of present-day Fort Wayne, Indiana, where it acted as a dam that heldback the waters of the lake. When the water was at its highest point, about 800 feet above sea level, it left beach ridges that later became the routes of trails and highways.
