At the eastern part of the "Going to the Sun"road, there was a "St. Mary Lake" which was the most beautiful and long lake along the "Going to the Sun" road, with reflections of glacier mountains and some cliffs here and there. There was a sightseeing cruise operated a few times a day. They wanted to take the cruise but the boat was not operative on the day unfortunately. As they didn't know when the boat can be repaired, they gave up the cruise and drove to north for Many Glacier Lake (officially, Swift Current Lake).
