haha...不仅全湖结冰，还有冬天自行车骑湖的trips.

我之所以说要查一下，是因为不敢肯定，湖是淡水还是海水。

看来湖水已经是淡水了，连峡湾里的水，也是表面淡水，下面海水的。

"When the ice cap melted, sea water invaded the region and formed the Laflamme Sea. In that era, salmon (saltwater fish) were bountiful in the region. Over time, the water receded, streams continued to flow into the Lac-Saint-Jean lowlands, and the lake water slowly lost all of its salinity. The Fjord, however, as it opens into the St. Lawrence River, is fed salt water downstream, and fresh water upstream.

Because salt water has higher density than fresh water, it flows under the surface water of the river. The surface of the Fjord (fresh water layer) freezes in winter, thus making it possible to build villages on ice. This creates a particular scenario as the sub-surface water is sea water, which means that we can fish for sea species while keeping warm in our fishing huts. The fresh water layer is all-important here because there would be no ice if there was only salt water, which does not freeze."

• 哇好棒。我隐约记得我好像在冰上骑过自行车，不过真的记不太清了，怕有吹牛之嫌，哈哈。 -mexicali- ♀ (0 bytes) () 08/24/2022 postreply 18:02:48
