How to survey
In northern Europe they are often still in good condition in hilly forest areas.
This is a list of indicators, but may vary from region to region:
- The site is a leveled circle or oval, usually 5 to 15 metres in diameter.
- Digging in the ground will reveal black mould, and tiny pieces of charcoal.
- The site is completely free of stone.
- Remains of a hut can often be seen near the perimeter of the site.
- Charcoal pile sites are usually found in areas around iron works.
- The site is near a water source, typically a stream.
- The site is placed so that gases will naturally ventilate away.
