May holiday sketches: Waterton Lakes National Park part 2

 Sketches from a 2 hour boat ride on Waterton Lake... on the water we crossed the US border on this cruise--my first time in the US in 12 years and my first experience of Montana. Because the scenery is always moving, it was a good opportunity to do some quick successive doodles, like cartoons, but I struggled with capturing any sense of the expansiveness of the whole experience.
