Thanks! The sunrise was quite spectacular that day and I enjoy using the Big Stopper every now and then just to see what might happen. I was especially pleased because I had a photographer friend from Missouri visiting and I wanted to show him a good spot for sunrises. Needless to say he was quite blown away by the show. This lake always has a couple patches of open water throughout the winter due to a natural warm spring in the area, which percolates to the surface. And it's sheltered enough that the water is usually calm even when it's a bit windy out. Really it's one of the best photography spots I've ever seen and it's only 30 minutes from my door. In other words, totally an unfair advantage . I'll post some other pictures from Jasper National Park in a separate thread. If any of you are thinking of doing a trip in my area, I can definitely point you in some directions for photo ops!
