Quick Summary

kame — kame Erratics with kames on the terminal moraine of the Okanagon Lobe, Waterville Plateau, Washington.

A terminal moraine is a ridge of glacial debris deposited by a glacier at its farthest extent. This accumulation of rock, sand, and clay, known as till, is pushed forward by the leading edge of the ice and dumped when the glacier stops advancing. Terminal moraines can form hilly terrain with knobs and kettles. They are a significant type of moraine, which are landforms created by the accumulation of material carried or deposited by glaciers.123
