outwash
Meltwater-deposited gravel
Outwash is sediment—sand, gravel, and other debris—deposited by meltwater streams flowing from a glacier.
The material spreads out in broad, flat plains called outwash plains: The valley floor consists of glacial outwash from the last ice age.
The term belongs to geology and glaciology.
