Two Jack Lake is a favorite stop for sunrises in Banff National Park and often warrants multiple visits. Why? The easy answer is Mount Rundle reflected when the lake’s water is still. The longer answer is that for all of the times I have been there, the cloud formations vary dramatically. I don’t know whether this observation is true or not but, when I visit, it certainly seems that way. On our visit last month, the clouds acted as leading lines to Mount Rundle and the reflection only magnified the effect.
