Packerton Moraine

The Packerton Moraine in north-central Indiana has been considered by most persons who have studied it to be a large interlobate moraine between the Saginaw and the Erie lobes. The northeast-southwest direction of the eskers north of Disko, Wabash County, and the southeast-northwest trend south of there indicated that the part of the Packerton moraine south of Disko was built by the Erie lobe and the part north of Disko by the Saginaw lobe. An esker, Miami County shows a northeast-southwest alignment, providing evidence that Packerton moraine in Miami County was built by the Erie lobe. A small area in the northwestern was deposited by the Saginaw lobe. It is named the Packerton moraine from the village of Packerton in Kosciusko County. Thirteen kames and eskers complexes are mixed with sand and gravel. The till is, sandier, especially in the part deposited by the Saginaw lobe, than in the lobe passed over some source of sand, whereas the Erie lobe did not. Water-laid or wind-blown sands are found throughout the moraine. The bulk of the sand seems to have been water-deposited, but locally the sand appears to have been reworked by the wind. Few of the sand deposits exhibit dunal forms.
