3.4.2 Small Lakes

The deposition of till or the abrasion of the bedrock can result in depressions suitable for creating small lakes. Many times the lakes form as deposition of till from a glacier in the main valley blocks the stream from a tributary valley. In cirques, the lakes that form in the rock basins are called tarns or cirque lakes. Down the valley from a cirque, other lakes sometimes form in a sequences as the deposition and erosion create small catchments for the water (so called paternostal lakes if arranged in this stepwise manner).
