One after another, the peaks of Kotli, Lower, Middle and Upper Kotel rise up towards the sky, forming a basin shaped, scenically varied barrier below the two Ponca mountains.
This is where the glaciers that once stood behind Za Akom on one side and behind Pod Srcem on the other side failed to carry these rocky features with them down the valley.
As elsewhere in this area, charcoal was also produced around Kotli. The clamps in which wood was burnt to form charcoal can be found almost everywhere near water, where there was a sufficient supply of suitable wood. Several dozen cubic metres of wood were needed to create one clamp. The charcoal was then sold to the iron works in Jesenice, for which it was an essential resource because iron ore was still being melted in foundries at that time. However, as technology progressed and other methods of producing iron production were discovered, the charcoal-burning industry was gradually abandoned.
Charcoal production was an additional source of income for local people. It was used by people who took over farms and other properties to pay the compensation they owed to their brothers and sisters who had to leave their homes.
