As well as regular geothermal activity, volcanic activity gives rise to large glacial bursts several times a century, which carry down large volumes of sediment. The materials in the outwash plain are size-sorted by the surface water of the melting glacier, with small particles like a slit, being the most distantly re-deposited, whereas the largest sediments are re-deposited to the original terminus of the glaciers. Higgins Lake, Gull, Cadillac, and many other lakes, are in An outwash plain is commonly smooth; where pitted, due to melt out of incorporated ice masses (pitted outwash plain), it is generally low in relief and largely retains its Glossary of landform and geologic terms The meltwater at the snout of the glacier deposits its load of sediment over the outwash plain, with larger boulders being deposited near the terminal moraine, and smaller particles travelling further before being deposited.
