I was blessed with some amazing light during a trip to Banff National Park a few years ago. This was especially true of Two Jack Lake. Being only about ten minutes from the hotel, I visited there twice and was treated to beautiful light each time. This contrasts with my visit a couple of years before when I visited the lake four times before getting decent light. As you can see, the light was amazing even though Mount Rundle was only partially lit (it never did get fully lit on this morning). Regardless, the clouds and the reflection more than made up for it. This is the reason you wake up at 3:30am for a June sunrise shoot.
