Rusty puddle
Rusty puddle
A dark red puddle on the track from Maesnant to Hyddgen LinkExternal link . Acidic bog water dissolves iron from rocks near the surface. As the solution flows into a puddle of less acidic rain water, the iron precipitates as iron(III) hydroxide Fe(OH)3, which manifests itself as a reddish-brown cloudy mess. When the puddle dries, it turns into iron oxide hydroxide FeOOH and finally into rust Fe2O3.
