Unembedded stream bottom
An unembedded north shore stream

This picture (courtesy of fotosearch.com) shows unembedded rocks; notice how even the smaller rocks are visible and not buried in sand and silt. Unembedded stones provide much more habitat space for stream critters to hide under. Fish eggs are better protected from predators when there is space for the eggs to nestle in crevices among the stones.
