Union Moraine

The Union Moraine begins in Ohio, east of Bellefontaine and the highest point in that state, (Campbell Hill, 1,549 feet (472 m))[1] towards Greenville in Darke County.

From Muncie, the moraine runs northwest ending in the bluffs overlooking Pipe Creek at Bunker Hill, Indiana, just south of Peru on the Wabash River.

[3] The moraine in east-central Indiana is covered with low relief ice-disintegration ridges and hummocks crossed by many ice-walled channels and eskers.

Reexamination of western Wabash County road cuts indicates that the clayey till is present there, but is generally less than 3 feet (0.91 m), thus within the leached portion of the soil profile.

Such a history would account for the loss of active ice features along the Union City Moraine in Delaware County and the presence of Lagro till on most of the segments of the Muncie esker system.
