Green Lake in Tragöss, AustriaEvery spring, melting snow creates a dreamscape in Tragöss, Austria. Green Lake, which for most of the year is no more than six feet deep, expands with the inflow of snowmelt, swallowing part of the park that surrounds it: trees, hiking trails, benches, bridges, and all. The lake's depth reaches some 30 feet and provides a unique experience for divers—for a few weeks at least.
