Fondovalle. A short diversion #1

Here is a short detour in a small marsh formed by the Adda river. Adda marshes receive water directly from the river or from its resurgences where the water gets filtered by the subtle granitic sands. The one depicted here receives waters in both ways. Being positioned near an hydroelectric plant is has a regime that somewhat resembles a natural one. Water levels more or less follow the natural ones albeit with some delays disastrous for the waterbird nests.

With this post I'm adopting a new frame. I've found that it better fits my idea of (post)modern postcard.
