Kames are formed when water flows over a glacier, and falls into crevasses within the glacier, leaving channels of sediment inbetween where the ice is. Once the glacier melts away kames are left behind and tend to be deposits of sand and gravel at the front of the melting ice sheet. These are unjulating unsorted mounds, as they tend to collapse when the ice around them melts away so they wont be supported.
Kame terraces are frequently found along the side of a glacial valley and are the deposits of meltwater streams flowing between the ice and the adjacent valley side. These kame terraces tend to look like long flat benches, with a lot of pits on the surface made by kettles. They tend to slope downvalley with gradients similar to the glacier surface along which they formed, and can sometimes be found paired on opposite sides of a valley.
