It flowed over the top of a recessional moraine at Browns Valley.
2.
In 1878, Clark used dynamite to breach a recessional moraine in the valley to drain a swamp behind it.
3.
One theory proposes that as the glacier melts it leaves behind an accumulation of rock debris in the form of annual recessional moraines.
4.
The composition of this proglacial region is reported to be a mixture of ground / recessional moraines with linear country outcrops protruding out.
5.
The Erie Plain lacks distinguishing features, except for occasional recessional moraines, and the remnants of proglacial lake beaches and lakeside cliffs.
6.
During these times, glacial lakes formed along the southern borders of the glaciers, bound into the Lake Michigan Basin by the recessional moraines.
7.
The Captain Islands off Greenwich, Connecticut, along with the Norwalk Islands and Falkner Island off Guilford, Connecticut are parts of a recessional moraine.
8.
Retreating glaciers often left recessional moraines that impounded lakes such as Lake Yosemite ( a shallow lake that periodically covered much of the floor of Yosemite Valley ).
9.
By then, observations of the stratigraphic relationship between varved sediment and recessional moraines, and the correlation of varve sequences between geographically distant sites, added more compelling evidence to De Geer's essentially circumstantial speculation.
10.
The Valparaiso Moraine is the dominant geologic form that created the various landscape forms of the Indiana Dunes, about 40, 000 YBP . Within the arc created by the Valparaiso Moraine are two younger recessional moraines of the Tinley Moraine and the Lake Border Moraine.
