Blenheim moraine
The Blenheim moraine is a glacial moraine in Kent County, Ontario, north of Lake Erie.[1]
Bluffs and beaches left from glacial lakes Arkona, Whittlesey, and Warren are found on the southern bank.[1]
The moraine's underwater extension is called the Erieau Ridge.[2][3]

In southeastern Kent County is an elevated area called the Blenheim moraine. As it forms a banana-shaped ridge about 20 metres above the generally low and flat areas of former lake bottom that form much of the county, it is the county's most prominent land form. Ridgetown is situated on the north edge of the moraine and takes its name from its setting, whereas the name of the moraine is after the town of Blenheim, located at the southwest end of the moraine.

The Erieau Ridge is capped by glacial drift and is interpreted as a segment of a morainic ridge.

Following this same path of correlation, the Erieau Ridge could be an offshore extension of the Blenheim Moraine, described by Chapman and Putnam (1951).
