when the glaciers slowed they first dropped boulders, then rocks, then stones, then gravel, then sand, then silt. you can see this along river valleys especially where the gravel and sand are being excavated commercially.
when Irene riled up our rivers, they tore out their banks (and a few houses, many trees, roads and bridges) and carried them off. as they slowed, they let go of it all. first boulders, then rocks, then stones, then gravel, then sand, then silt. you can see this in my back yard.
