游侯

一天里最印象深刻的是EMERALD湖。比LOUISE大。我们绕湖一周。３。２英里。一边是干，热，草枯叶黄，太阳晒着一切，只有松树是绿的。我们拍着蜘蛛网，和艳红的叶子，顶着太阳，没有太多的好心情。直到我们到达湖底，景色大变。我们走进了树林，湿润的空气，绿的草，绿的树，绿的苔藓。这是湖的另一面。因为太阳光，湖的两边是全然不一样的环境，不同的植物生长在两边。一边阴，一边阳。我们的相机不能完全描述两边的差别。

Yoho

Bow lake, Bow summit, Peto lake. Not very impressive. Cold morning.

We visited Yoho, solely to see the Emerald Lake. It's much bigger than Lake Louise. We hiked around the lake, 3.2 mile. The trail along one side of the lake is dry, burn by sun. But the other side is misty, full of moss, underbushes. Let info tells the story:



"water has affected this valley by its absence as well as its presence. This forest, strewn with needles and lichens, receives less rain than the opposite shore and gravelly soild it grows on quickly carries away what rain it does get. In summer, the sun beats directly down on this slope, sucking moisture from the plants and the soild. As a result, the plants here captures moisture quickly and hoard it tenaciously in order to stay alive. This is not the case in some other parts of valley, where, as you will see, conditions are wetter."
--
"you have reached the end of the lake - nearly the half way point on the trail and a place where water is working to landfil the lake it created as glacial ice and metlwater thousands of years ago. Fast-flowing streams sunddenly slowed where the valley flattens, dump loose rocks and coarse gravel to form this plain. The growth of this alluvial fan is especially rapid in late spring when runoff is at its peak. The fan will grow until the lake is completely filled. It may tkae as long to fill in the lake as it took to carve it out but the disappearance of Emeradle lake is inevitable."



Revisit Bow Valley parkway, muleshoes meadow, met two celebrated local photographers (with big cameras). Pilot pond. Ugly. But the short trail is indeed steep. Spiced the hike of the day up a bit.

Dinner: Banff Italian, Guidio. so so.
