At first glance， these photographs seem to show a scuba[水下呼吸器] diver[潜水者] exploring the depths of an underwater world. But if you look more carefully you will see a tree， a bridge and even a park bench.
In fact these incredible[难以置信的] images show a diver crossing an Austrian lake that floods every year， covering everything in the surrounding area.
Set among the snowy Hochschwab Mountains， the Green Lake in Tragoess， Austria， is normally only one metre deep.
For most of the year， visitors to the scenic[景色优美的] spot can stroll[闲逛] around the beautiful lake， enjoying the stunning[极好的] landscape from one of the benches set near the water’s edge. They can wander[漫步] down several footpaths[人行道] and cross one of many small bridges. But every year from mid-May to June， when the snow melts， the lake floods and submerges[浸没] everything surrounding it.
Around 12 metres of water covers trees， footpaths， benches and bridges. Gallons of clear， 7°C water doubles its size from 2，000sq metres to over 4，000sq metres.
Diver Marc Henauer， from Perly， Switzerland， heard about the natural event and came to explore the lake for himself.
The 39-year-old said， “When I was underwater， it felt like I was swimming in a magical world， it was so beautiful. Swimming over the green grass， flowers， paths， rocks and trees was like being in a fairy tale.
“We were lucky that the sun created fantastic[極妙的] light rays through the water. My wife and I stayed there for seven days and we did three dives every day， spending one hour on each dive.”
He added， “We only had a very short time to take images when the sun was in a perfect position. Diving is possible only for a month in the spring. Throughout the year the depth of the lake is too low. The visibility[可见度] is just incredible. Usually you only see water like this in tropical[热带的] seas.”
乍看之下，这些照片似乎展示了一名潜水者正在探索海底世界。但仔细观察的话，你会看到图中不仅有树，有桥，甚至还有公园的长椅。
事实上，这些神奇的照片展示的是一名潜水者在一个奥地利的湖泊里潜游的情景。每年，这个湖的湖水都会暴涨，把周围的一切完全淹没在水中。
翠湖位于奥地利特拉古斯白雪皑皑的上施瓦布山当中，平时水深只有一米多。
一年中的大部分时间，来到该景区的游客都可以在美丽的湖边漫步，坐在湖边的长椅上欣赏令人叹为观止的美景，也可以沿着数条小径漫步，穿过多座小桥。但在每年5月中旬至6月期间，山上的冰雪消融，湖水便会暴涨，淹没周围的一切。
约12米深的湖水会把树木、人行道、长椅和小桥统统淹没。大量水温为7摄氏度的清澈融水将湖面从2千平方米扩大到4千平方米，扩大了整整一倍。
来自瑞士佩尔利的潜水者马克·赫诺尔听说了这一自然现象，特地前来一探究竟。
39岁的马克·赫诺尔说：“在水里我感觉就像在一个奇幻世界里游泳，它是如此美丽。从青草、鲜花、小径、岩石和树林上方游过，就像在童话世界里一样。
“我们很幸运，阳光穿透湖水，投射出梦幻般的光线。我和妻子在那里待了七天，每天潜水三次，每次潜一个小时。”
他补充道：“我们要趁太阳处于完美的角度时抓拍照片，所以时间很短。一年四季只有春天里的一个月适于潜水，其他时间湖水都太浅了。湖水的能见度高到难以置信。通常只有在热带海域才能看到如此清澈的水。”
