Aerial photo of Lake Zelenci, Slovenia
Fresh, never frozen
An alpine forest's brilliant green palette is the perfect complement to the aquamarine tones of Lake Zelenci, but the water's intense colour isn't limited to the verdant summertime. Since it's fed by a natural underground spring, which bubbles up through the Swiss-cheese lakebed flecked with tiny holes, the lake keeps a fairly constant temperature of just above 4 degrees Celsius. Thus, even in the harshest Slovenian winters, these painted waters never turn to a blank canvas of ice.

Next time you describe something super unlikely, try using the analogy "when Lake Zelenci freezes over".
