Lake Louise: Hiking to the teahouse

Decided to Travel Alberta this year. I went hiking from Chateau Lake Louise. From Lake Louise you can hike 6.4 km and follow the glacier scour to the base of the mountain called 6 plains on the Glacier. Due to global warming the glacier has melted from Lake Louise to the base of the mountain where the Glacier originates. At the end of the 6.4 km climb there is a two story log teahouse that is similar to the Skoke Lodge that Prince William and Lady Katherine visited in the Kananaskis. Along the trail you will meet people from all over the world who do not speak English as their native tongue who cannot believe the wilderness experience that I take for granted. Sometimes on the 3 foot wide path there is a steel cable bolted into the cliff face that you should hold onto to keep you from falling down the 1000 foot vertical cliff on your right.
At the teahouse, there are three or four college students whose summer job is to run the teahouse.
Because the students have to work until 5 pm they trek down the mountain to go to the town of Banff to relax. The students have to daily backpack out all the garbage to the town of Banff and then do grocery shopping. All the groceries for the teahouse must be carried by backpack up to the teahouse. These young students sometimes end up trekking back to the teahouse at 12 midnight because they want to socialize but they have to open up the lodge for trekkers in the morning.
Hiking in the mountains at night is not a good idea because creatures of the night come out such as porcupines, cougars, coyotes and bears and they can see , hear and smell much better than humans in the pitch black night. And of course there is the 1000 drop to your death off the cliff if you miss a step.
