Are you really sure Archa Noah's landed on Ararat? Prokopské údolí (St.Prokopius Valley), Praha

I have a seven-year-old son. So I often look at Prague through playgrounds. But the Prokop valley is also an amazing geological location. It's the half-billion-year-old ocean bottom. After the rain, and when you're lucky, you can find fossils of ammonites, trilobites ... And there's a beautiful one.
