From Ohio History Central

Kames are conical hills composed of sand and gravel that have been sorted by water. They are ice-contact deposits that formed when glacial meltwater poured into a hole in the ice or when meltwater poured over the snout of the glacier. The meltwater carried sand and gravel and built it up into piles that formed the conical mounds typical of kames. These features are common in the Akron area and south of Columbus along U. S. Route 23.
