A peat bog surrounds the area around the source
A bog is a wet land (wetland) habitat. Bogs can be dangerous places because, although they can look (and sometimes feel) like land, in fact they are more like a spongy "floating carpet" of land. Underneath the surface, bogs are full of water - about 90-95% water.
Most of the water from all around here will help the River Severn grow
Peat is a soil that is made up of the partially decomposed remains of dead plants (partly rotted roots, branches, leaves and seeds) which have accumulated on top of each other in waterlogged places for thousands of years.

Can you see the footsteps in the bog?
Peat is brownish-black in colour and in its natural state is composed of 90% water and 10% solid material.
Water trickles off this saturated (waterlogged) land to join other 'trickles' known as gullies or rills, these eventually join with other gullies and form small streams. The streams flow together to make the beginnings of the River Severn.
Water always flows downhill by gravity.
Gully or Rill
