The solstice has passed and with that comes longer days. The waning and waxing of sunlight throughout the year creates the change we see in the world around us. Set in the Alps of Austria, Der Grüne See or The Green Lake exemplifies how spectacular seasonal change can be. For half the year the park houses a beautiful lake complete with hiking trails and picnic benches, but once the glaciers hanging above start to warm up the valley that holds this lake becomes flooded into a scuba divers paradise. The seemingly normal park becomes a surreal submerged world waiting to be explored.
